The 8640x8640 matrix that you are trying to build requires about 600MB of RAM (contiguous), which should not be an issue on a 64bits system.

What system are you using? Run the command

 memory

to see what the maximum array size is (contiguous memory).

Well, cmd memory should indicate that you have less than 600MB of contiguous memory available for storing arrays.

I withdraw my previous comment, when I tested a'*a , memory used by Matlab was already occupied,
