* chore: Rename `apply` to `mapSlices`
This renaming conforms with the Julia name for the function formerly
called `apply`, and allows it to be called from the expression parser.
The previous name `apply` is kept as an alias for `mapSlices`, for
backward compatibility. This commit implements an `alias` metadata
property for function factories to facilitate the `apply` alias for
`mapSlices`.
As a separate bonus, this PR corrects several typos in function docs
and removes now-passing doc tests from the list of "known failing" doc
tests to get down to 45 known failures and 136 total issues in doc tests.
(Most of the excess of 136 as compared to 45 are just due to roundoff
error/slight inaccuracy of what the documentation claims the result will
be and the actual result returned by mathjs. When the 45 are eliminated,
a reasonable numeric tolerance can be decided on for doc testing and
then the doc tests can be made binding rather than advisory.

* feat: add polynomialRoot function
This is intended as a benchmark for general arithmetic/basic algebra
functionality of mathjs, but was chosen to be something of potential
independent utility as well, worth adding to mathjs in its own right.
Currently ol=nly computes the numerical roots for real or complex
polynomials of degree three or less.
As usual, adds documentation, embedded documentation, tests, TypeScript
declaration, and TypeScript tests.
Also updates doc.test.js to make it easier to specify an array of complex
numbers as the expected output, and comapres with the appropriate fuzz
in such cases.
Finally, adds a benchmark that computes the roots of all cubics with
nonnegative integer coefficients no larger than five.

* refactor: Remove the automatic conversion from number to string. (#2482)
This is a breaking change. However, nothing in the unit tests or examples
actually depended on such a conversion, and it's difficult to construct
situations in which it's necessary. The best such example is e.g.
`count(57)` which formerly gave the number of digits in its numeric
argument. Of course, after this commit, that behavior can still be
obtained by the just slightly longer expression `count(string(57))`
The change is proposed in preparation for an addition of new facilities/
handlers to allow symbolic computation in a couple of different ways
(see #2475 and #2470).
* feat(simplifyCore): convert equivalent function calls into operators (#2466)
* feat(simplifyCore): convert equivalent function calls into operators
Resolves#2415.
* docs: Every operator has a function form
Also documents the new behavior of simplifyCore to convert function calls
into any equivalent operator form they may have. Also fixes the syntax
errors so that simplifyCore will successfully doctest.
* docs: Fix table syntax for operator->function correspondence
* fix(parse): Implement amended "Rule 2"
As per the discussion in #2370, the amended "Rule 2" is
"when having a division followed by an implicit multiplication, the
division gets higher precedence over the implicit multiplication when
(a) the numerator is a constant with optionally a
prefix operator (-, +, ~), and
(b) the denominator is a constant."
This commit implements that behavior and adds tests for it.
Resolves#2370.
* fix: OperatorNode.toString() outputs match implicit multiplication parsing
Also greatly extends the tests on OperatorNode.toString() and .toTex(), and
ensures that all tests are performed on both. (toHTML() is still a testing
stepchild.)
Also fixes other small bugs in .toString() and .toTex() revealed by the
new tests.
Resolves#1431.
* test(parse): More cases of implicit multiplication
* refactor: Alter the precedence of implicit multiplication
This greatly simplifies OperatorNode:calculateNecessaryParentheses,
as opposed to trying to correct for the change in precedence after
the fact.
* Fix broken unit test
* Replace `options && options.implicit` with `options?.implicit`
* Replace `options?.implicit` with `options && options.implicit` again, it breaks the Node 12 tests
* chore: Prevent confusion with standard matrix functions. (#2465)
* chore: Prevent consfusion with standard matrix functions.
Prior to this commit, many functions operated elementwise on matrices
even though in standard mathematical usage they have a different
meaning on square matrices. Since the elementwise operation is easily
recoverable using `math.map`, this commit removes the elementwise
operation on arrays and matrices from these functions.
Affected functions include all trigonometric functions, exp, log, gamma,
square, sqrt, cube, and cbrt.
Resolves#2440.
* chore(typescript): Revise usages in light of changes
sqrt() is now correctly typed as `number | Complex` and so must
be explicitly cast to number when called on a positive and used
where a Complex is disallowed; sqrt() no longer applies to matrices
at all.
* feat: Provide better error messages for v10 -> v11 transition
Uses new `typed.onMismatch` handler so that matrix calls that used to
work will suggest a replacement.
* Fix#2412: let function diff return an empty matrix when the input contains only one element (#2422)
* Fix#2412: let function diff return an empty matrix when the input has only one element
* Undo changes in History in this fixme
* Add TypeScript definitions for src/utils/is.js (#2432)
This is a first step toward full publication of these functions,
that were already being exported by mathjs but had not yet
had the associated actions (documentation/available in
parser/typed, etc.) Also, makes most of them into TypeScript
type guards, and adds Matrix as a constructor type. Resolved#2431.

* Refactor/simplify core cleanup (#2490)
* refactor: don't simplify constants in simplifyCore
Keeps the operation of simplifyCore cleanly separate from
simplifyConstant.
* fix; handle multiple consecutive operations in simplifyCore()
Also adds support for logical operators.
Resolves#2484.
* feat: export simplifyConstant
Now that simplifyCore does not do any constant folding, clients may
wish to access that behavior via simplifyConstant. Moreover, exporting it
makes it easier to use in custom rule lists for simplify().
Also adds docs, embedded docs, and tests for simplifyConstant().
Also fixes simplifyCore() on logical functions (they always return boolean,
rather than "short-circuiting").
Resolves#2459.
* refactor: Rename matrix algorithms to stay sane in next refactor
* refactor: Create a generator for boilerplate matrix versions of operations
This reduces code length and duplication, and significantly reduces the
number of instances of 'this' that will require replacement when moving on
top of typed-function v3.
* refactor: add automatic conversion from string to Node
Eliminates many `this` calls in src/function/algebra, which will help
conversion to typed-function v3a.
Also make `resolve` into a typed function so that it will now work
on strings as well, and adds a test that it does.
* refactor: Use temporary conversions to simplify typed-function definitions
Specifically, temporarily converting Object to Map eases the definition
of 'simplify' and a new, generally ignored type 'identifier' (a subtype
of 'string') with a temporary conversion to 'SymbolNode' simplifies the
definition of 'derivative'.
These refactors eliminate multiple instances of this, which will ease
conversion to typed-function v3a.
* refactor: Speed up utils/is.js typeOf function
In preparation for using it as the function selector for the Unit class.
Also fixes the inconsistency between the `typed` type hierarchy
'function' and typeOf returning 'Function' in favor of
'function', again to minimize the special cases in typeOf
* feat(Unit): Add a method giving the (string name of the) type of the value
E.g. `math.unit('5cm').valType()` returns `number`.
Also uses this for an internal method that directly gives the number
converter for a Unit.
Also fixes lint errors from previous commit (not clean, I know, I forgot
that build-and-test does not run lint).
Adds tests for unit.valType()
* refactor: Eliminate hyperbolic functions operating on angles
There is no mathematical meaning to a hyperbolic function operating on
an angle (the proper units of its argument is actually area), and it
eliminates a number of uses of `this`, so remove such arguments.
* refactor: Remove miscellaneous unnecessary typed-function this refs
* refactor: Adapt to typed-function v3a
Mostly this involves replaceing instances of 'this' with used of (preferably)
typed.referTo() or typed.referToSelf(). Some repeated batterns of boilerpolate
signatures within different divisions of functions (bitwise, relational,
trigonometry) were factored out into their own files and reused in several
of the individual functions.
* tests: Only require that derivative tests mention the proper node type
* refactor: remove typed.ignore
* chore: Update to typed-function 3.0
Also had to deal with new typing for `resolve()` in that it now accepts
strings and Matrices; added tests for the new possibilities for `resolve()`,
and eliminated empty comments from the Node representation of parsed
strings as they can't really be doing anyone any good and they are a pain
for testing.
Also updates the TypeScript declarations and tests for `resolve()`
* chore: Object.hasOwn not supported in Node 14
Also removes 'resolve' from the known failing doc tests, now that it handles
strings.
* chore: Drop ES5 / IE 11 support.
* fix(types): Remove no-longer-implementd matrix overloads
* test(identifier): As requested in review item 2
* refactor(Unit): valType => valueType as per review item 3
* test(hasNumericValue): Test boolean arguments as per review item 4
* refactor(Node): Use class syntax rather than assigning prototypes
This change simplifies the typeOf() function, because now all subclasses
of Node have the expected constructor name.
Also, reformats the documentation of the typeOf() function so that the
doc test of that function will serve as an exhaustive test that the bundle
returns the proper types.

* feat: Provide better error messages for v10 -> v11 transition
Uses new `typed.onMismatch` handler so that matrix calls that used to
work will suggest a replacement.
* fix: prevent chain from matching rest parameter with stored value
Since the revised code needs the isTypedFunction predicate, switch to using
the typed-function implementation for that throughout mathjs, rather than
rolling our own here.
Also adds a test that chain() no longer allows this kind of usage.
Removes the two type declarations in types/index.d.ts that were allowing
this sort of "split rest" call and added tests that such calls are
forbidden.
Adds to the chaining documentation page that such "split" calls are not
allowed.
* chore: Refresh this PR to reflect underlying changes
Also addresses the review request with a detailed comment on the
correctness of a new code section.
Note that it reverts some changes to the TypeScript signatures of the
matrix functions ones() and zeros() -- they do not actually have a
typed-function signature of two numbers and an optional format
specifically for two dimensions. What they have is a single rest
parameter, from which the format is extracted if present.
Hence, due to the ban on breaking rest parameters, it is not
valid to call math.chain(3).zeros(2) to make a 3-by-2 matrix of zeros,
which seems like a perfectly valid ban as the division of the dimensions
is very confusing; this should be written as math.chain([3,2]).zeros().
The TypeScript signatures are fixed accordingly, along with the edge
case of no arguments to ones() and zeros() at all, which does work to
produce the "empty matrix".

Uses the existing extraction of examples from tools/docgenerator.js
Hence, for now this is limited to documentation of functions, but
hopefully it can be extended to classes, units (and physical constants),
and constants as well in the future.
Exposes numerous errors in the examples, some of which are bugs; these
are for now put on a known error list to be worked on, so that this
PR does not change a huge number of source files.
Also adds a test to check that all symbols are documented (which
similarly doesn't really pass at the moment, and is patched to a
hopefully temporary warning).
* refactor: Make doc.test.js into a node test
The source code is not available in its layout as in the repository in
the browser tests, so the new doc testing can only occur in the node tests
* Add simplifyCore, symbolicEqual, map, and resolve to the list with functions with known issues in the jsdoc examples
