Help! My Mathlink program eats up too much memory! I am currently having memory problems when trying to run a Mathlink'd C program in Mathematica v. 5. I use Mathlink to call an external C program to solve a large sparse matrix. The problem I am having is that according to the Task Manager, the external C code uses a lot of memory (mostly virtual memory), >500MB! Based on the matrix size 73x73, I expect the code to use far less memory. I also searched the net for similar problems. I found one in which the user had to clear a cache directory. I can't find a cache directory. How do I keep my Mathlink C program from using so much memory? Thanks, Lawrence
