Hey, @kgryte, don't know why the test case inside test.main.js and test.ndarray.js for N < 0 is giving an error.

	drotm.main( -1, x, 1, y, 1, param );

Error message:

# if provided an `N` parameter less than or equal to `0`, the `main` method leaves both input arrays unchanged
/home/aman/stdlib/lib/node_modules/@stdlib/strided/base/write-dataview/lib/ndarray.js:103
                view[ m ]( iv, data[ ix ], littleEndian );
                         ^

Using all zeros for the parameters is not a particularly "interesting" example.

@aman-095 Looks like there is a bug in what we are passing to strided2object. Namely, it naively assumes that N is a nonnegative integer:

stdlib/lib/node_modules/@stdlib/strided/base/strided2object/lib/main.js

Line 45 in 7df5877

* @param {NonNegativeInteger} N - number of indexed elements

My guess is that we should update

stdlib/lib/node_modules/@stdlib/strided/base/strided2object/lib/main.js

Line 76 in 7df5877

obj.length = N;

to

- obj.length = N;
+ obj.length = ( N > 0 ) ? N : 0;

This PR will need to incorporate various docs and build changes as made in other blas/base/*-wasm packages recently.
