[Octave-bug-tracker] [bug #61674] deconv much slower than conv

[Arun Giridhar]

Follow-up Comment #11, bug #61674 (project octave):

Patch 4 attached to split up the loop into outer and inner as mmuetzel
suggested. Also moved some loop invariants out of their respective loops.
Performance is almost as fast as Patch 1. Please test and see how
interruptible this code is. I think the sweet spot for num_inner is somewhere
between 30K and 300K and it can be tuned as needed. Passes BISTs.
