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

[Markus Mützel]

Follow-up Comment #10, bug #61674 (project octave):

Not sure if this will make a difference. But have you tried to create an inner
loop without `if` conditionals and an outer loop that contains the octave_quit
function call?
Something along the lines of

int some_big_number = 100000;
int n_inner_loop = 1000;
for (int i_outer = 0, i_outer < some_big_number/n_inner_loop, i_outer++)
{
  for (int i_inner = 0, i_inner < n_inner_loop, i_inner++)
  {
     do_the_actual_work
  }

  octave_quit ();
}


Obviously, we'd need to put a little bit more thought in to get the number of
inner loop runs correct. But maybe that would allow the compiler to optimize
the inner loop while still having the outer loop interruptible...
