I need to calculate the autocorrelation coefficients for a vector of 744
elements, but `xcorr` fails returning this error message:
error: out of memory or dimension too large for Octave's index type
error: called from:
error: /home/$user/octave/signal-1.3.2/xcorr.m at line 203, column 7
The behaviour can be reproduced with:
var = stdnormal_rnd(744);
[r, lg] = xcorr(var, length(var)/2-1);
Can nybody help to fix this problem?
It works for me but the answer is very big
size(r)
ans =
743 553536
numel(r)
ans = 411277248
that is 411,277,248 doubles stored in memory
