* fix qr and sign edge cases
qr() was throwing an error if the pivots of a matrix were zero.
This commit fixes that and ensures that the results are consistant
with wolfram alpha.
Whilst doing this I found a bug in complex.js, I have added a work
around but we should flag this upstream.
I also addressed the long standing concerns about assert statements
within the body of the qr function.
Fixes#1669Fixes#942
* further improvements to qr and sign
mainly fixing things I got wrong in previous commit
* add array test
* fix: remove only from tests and disallow
Uses mochas `--forbid-only` flag as advised by
https://github.com/standard/standard/issues/988
* Allow taking means of quantities with units.
* Fix silly error in test.
The test as written did not test anything about units.
* Fix same error again...
* Implemented the `multicombinations` function
* Write unit tests for `multicombinations` function
* Integrate the `multicombinations` function throughout codebase
1. Include multicombinations factory function in factoriesAny.js and factoriesNumber.js
2. Write embedded docs for multicombinations
3. Added latex support
4. Refer to multicombinations in the "see also"-section of related functions
* Change name from `multichoose` to `combinationsWithRep`
* Update combinationsWithRep.js
Instead of always cancelling `n-1 factorial` from the denominator and ignoring `k factorial`, added a conditional to cancel the the larger of the two, therefore further reducing redundant calculations.
* Revert "Update combinationsWithRep.js"
This reverts commit efef6d3bd4c381aa12f00869a7624a622268805c.
* Update combinationsWithRep.js
Instead of always cancelling `n-1 factorial` from the denominator and ignoring `k factorial`, added a conditional to cancel the the larger of the two, therefore further reducing redundant calculations.
* Add one more test for the case: k > n-1
* Refactor single for-loop into two separate ones
