[Octave-bug-tracker] [bug #63791] movmean - out of memory or dimension too large for index type

[Liang Tang]

Follow-up Comment #15, bug #63791 (project octave):

I will not go into discussion of the filter approach.  I did repeat Dmitri's
examples in a different order, movmean is the last one:

>>
>> a= rand(1e6,1);
>> N = 513;
>> tic; c = filter(ones(1,N)/N, 1, a); toc
Elapsed time is 0.527736 seconds.
>> tic; d = filtfilt(ones(1,N)/N, 1, a); toc
Elapsed time is 1.39225 seconds.
>> tic; b = movmean(a, N); toc
error: out of memory or dimension too large for Octave's index type
error: called from
    movfun>movfun_oncol at line 299 column 10
    movfun at line 282 column 14
    movmean at line 138 column 5
