9a63e0e82e Bugix for Frobenius norm of complex matrices. 
Also improve efficiency from cubic to quadratic by avoiding taking
the trace of a mat-mat multiplication, and rather just summing the
formula for the diagonal entries.

Include a unit test to avoid regressions.

308d55dac4 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
