Depends on f, which presumably is some mathematically-defined function not already part of Mata. Yes, in the sense that you can write a Mata function to make this possible. But I suspect that in most cases you would need to loop over the rows and columns inside the function any way, which in a way is saying No. Otherwise, pointers may be what you are looking for. Nick n.j.cox@durham.ac.uk Thomas Alexander Stephens I'm using Mata in Stata 12. Given a matrix A and a scalar function f, which has no side effects, I'd like to compute a matrix B with B[i, j] = f(A[i, j]). Since there are no side effects, I'd like to run the elementwise computations in parallel. Is this possible? * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
