The requested array exceeds the preset maximum array size

[lperkk]

Hey，
When I used the 'som_make': [sMap,D] = som_make(D, varargin) (The dimension of my input matrix D is 63*90816), then MATLAB reports an error:
Requested 90816x90816 (61.4GB) array exceeded the preset maximum array size. Creating arrays larger than this limit may take longer and cause MATLAB to be unresponsive.
Error in som_liminit(line 222)
A = zeros(dim);
Error in som_make (line 298)
case 'lininit', sMap = som_lininit(D, sMap);

How to handle input data with lots of columns for som training?

Thanks!
