And the results for a 65x65 set of linear equations are... ?
They are...whatever you get? It takes longer to enter than to process. In that size, of course, you'd automate the process by loading a file, which is another single function.
There's an awful lot in MATLAB, and it's all right there, a function away. You might like it a lot better than plodding everything in PS. I bet you could find the next 666 bit magic sinewave in a few minutes.
