Adds matrix function math.sqrtm(A) ( #1086 )
...
* Adds Matrix function math.sqrtm(A)
The current implementation is based on the Babylonian iterative method
* Removing default parameter as they are only supported from ES6/ES2015 onwards
* Increases the robustness of the `math.sqrtm()` Babylonian iterative method
* Adds Denman–Beavers iteration method to compute `X*X = A`
The Babylonian method is numerically unstable and more likely to fail to converge. For that reason, the Denman–Beavers iteration method is the one being used in the current version.
* Adds LaTeX for math.sqrtm(A)
* Updates `math.sqrtm(A)` suggestions list
* Forgot to require latex...
* Adds unit tests for `math.pow(math.sqrtm(A), 2) == A`
* Switches from SyntaxError to Error
Edits error message
* Adds unit tests for non-square matrices and LaTeX conversion
* Changes according to feedback
- Removes Babylonian method implementation;
- Adds unit tests for BigNumber matrices
- sqrtm.test.js refactoring
- Edits LaTeX conversion
* Ensures input/output type persistence
* Changes math.deepEqual to assert.deepEqual (or to approx.deepEqual where appropriate)
* Fixes BigNumber unit test
