I have a audio matrix of size 77720 X 1. I have to multiply it with a image matrix.I have converted image to 1D and change its type to double so that both matrices are of same type.Image matrix size is 1 X 77720. Both matrices are of type double.
Error using ==> mtimes
Out of memory. Type HELP MEMORY for your options.
this is the error I am having when I do mul=a*b

Your result is a 77720x77720 double array, which is almost 50 Go of data, it can not be handled by Matlab. to know your limits, Type
memory

Sure.
IM = rand(1, 77720);
IM = IM([]); % reduces it to a 0-by-0
Perhaps if you describe in more detail exactly what you're hoping to compute with this multiplication someone can offer suggestions about how to do what you want without creating a 50 GB matrix.
