where_not_allclose

astropy.utils.diff.where_not_allclose(a, b, rtol=1e-05, atol=1e-08)

A version of numpy.allclose() that returns the indices where the two arrays differ, instead of just a boolean value.

Parameters:

a, b : array_like

Input arrays to compare.

rtol, atol : float

Relative and absolute tolerances as accepted by numpy.allclose().

Returns:

idx : tuple of arrays

Indices where the two arrays differ.
