[Numpy-discussion] offset in fill diagonal

[josef.pktd at gmail.com]

Is there a simple way to fill in diagonal elements in an array for other
than main diagonal?

As far as I can see, the diagxxx functions that have offset can only read
and not inplace modify, and the functions for modifying don't have offset
and only allow changing the main diagonal.

Usecase: creating banded matrices (2-D arrays) similar to toeplitz.
