Function Documentation

NPY_NO_EXPORT void PyArray_CreateSortedStridePerm	(	PyArrayObject *	arr,
		_npy_stride_sort_item *	strideperm
	)

This function populates the first PyArray_NDIM(arr) elements of strideperm with sorted descending by their absolute values. For example, the stride array (4, -2, 12) becomes [(2, 12), (0, 4), (1, -2)].

Set up the strideperm values
