Hi all, I am working with a very large matrix [640x640x640] I had to convert from double to single in order to be possible to acomodate it in memory. Due the fact that Matlab do a copy of the input arguments in function I am not able to work with the matrix in a recursive function. So I solved the problem working with global variable. second problem was the recursion I had to extend the limit of 500 for recursivelly calling of the function, but Matlab crashed.. Now I am considering to use Mex. But in my readings (net, Matlab docs, etc..) tells me that I can not work with the memory address of the matrix in order to alter it. My question is, I am right?

You *can* do it, possibly with some trickery to throw off some
compiler safeguards. At your own risk, of course.

The better way is to divide the problem and work on many smaller
matrices.
