[Octave-bug-tracker] [bug #39378] randperm cannot handle large arguments

[Jordi Gutiérrez Hermoso]

Follow-up Comment #2, bug #39378 (project octave):

I had some reason for capping the size of M. My reasoning was that if M was
big enough, you might as well just allocate the full vector for speed. Perhaps
a more sophisticated approach would be to do


bool short_shuffle = (m < n/5 && m < 1e5) || double(m) >
double(std::numeric_limits<octave_idx_type>::max());


?
