I am working with signals that are segmented into 63 secs length, sampled at 128Hz, which means there are 8064 sample points per segment.
One of the parameters of 'bispecd' (of the HOSA toolbox) defines 'segsamp' - number of samples per segment. The bispectrum matrix is thus very large (8192x8192) and MATLAB gives me an Out of Memory error while trying to perform the calculation.
Is there a work around to this problem? It might also be the case that I am reading the semantics of the parameters wrong. Would greatly appreciate if a solution could be posted or my understanding of the parameters disabused.
I am running MATLAB 7.8.0 (2009a) 32-bit version on a HP Z800 workstation
Thanks

Please post the complete error message accompanied by the relevant part of your code.
The 8192x8192 double array consumes 536 MB Ram. Do you have enough free memory for this?
The standard suggestions remain as usual:
