[Octave-bug-tracker] [bug #63791] movfun - high intermediate memory use

Subject: [Octave-bug-tracker] [bug #63791] movfun - high intermediate memory use for moderate data input resulting in out of memory errors

Follow-up Comment #28, bug #63791 (project octave):

@Liang: Yes, only the input (x) is single which is why I mentioned there is
something else going on.  If the input is single, the output should also be
single, but this is not the case for Octave.


class (movmean (single (1:3), 2))
ans = double


Matlab correctly returns an object of class single for this example.

This is a functional error that needs to be corrected, and when it is it will
also decrease memory usage.
