	> LAPACK routine to compute the value of the one norm, or the frobenius norm, or the infinity norm, or the element with the largest absolute value of a real matrix `A`.

Applies here and everywhere else in this PR.

[kgryte]

Suggested change

	The `dlange` routine computes the value of a specified norm of a real M-by-N matrix `A`. The norm to be computed is selected using the parameter `norm`, which may specify the **Max norm**, **One norm**, **Infinity norm**, or **Frobenius norm**.
	This routine computes the value of a specified norm of a real M-by-N matrix `A`.

[kgryte]

Suggested change

	- **norm**: specifies the type of norm to be calculated, should be one of the following: `max`, `one`, `frobenius`, or `infinity`.
	- **norm**: specifies the type of norm to be calculated, should be one of the following: `'max'`, `'one'`, `'frobenius'`, or `'infinity'`.

For string literals, always enclose in single quotes. Otherwise, ambiguous the value type. Here, infinity could mean 'infinity' or the numeric literal infinity. Enclosing in quotes makes this explicit.

[kgryte]

Same comment.

Suggested change

	* @param {Float64Array} work - work array, should have `N` indexed elements if row-major layout is used
	* @param {Float64Array} work - workspace array

This can be replaced with a call to blas/ext/base/dfill.

[kgryte]

This can be replaced with a call to stats/strided/dmax.

If sum is NaN, we should immediately return, as value will never be less NaN.

[kgryte]

Same thing. If temp is NaN, we should immediately return NaN. No need continuing.

[kgryte]

I believe this should be abs( A[ ia ] ). This should have been caught during testing, which means there is a gap in the tests.

[kgryte]

Same thing return NaN handling.

You can replace with a call to blas/ext/base/dfill.

Is it me or is the infinityNorm just the oneNorm with A transposed? If so, can we just consolidate implementations into a single function and then have oneNorm and infinityNorm be light wrappers which swap the strides as necessary?

[kgryte]

Rather than disable the lint rule multiple times in this file, just go ahead and disable once above the 'use strict' directive.
