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

[Jordi Gutiérrez Hermoso]

Follow-up Comment #4, bug #39378 (project octave):

No, I meant double(n) > ..., rather. The problem is that if the full size of
the vector is too big, then there's no hope that the "long" shuffle can work,
because then line 1149 fails:

In this case, we must do a short shuffle.
