wrong variable in comparison code for verification

[jimburtoft]

the code will always print "NKI and NumPy match" even when they might actually differ. The comparison needs to be between the NKI output (out_nki) and the NumPy output (out_np) to properly verify if they produce the same results.

Not sure if this shows up in a doc or test anywhere else.

Testing:

Please see detailed unit test requirements in the CONTRIBUTING.md
