The problem is, matlab, when called from another program, spawns a separate matlab engine process. The data we are working with can get very large (4gb+) so we can't pass copies of it around. We are looking at using cygwin's shared memory functionality to get around this on windows (NT derivatives only). My question relates to the implementation of shared memory in cygwin. Copies of the data won't work (even to move it to another process space) and we would prefer not to deal with on disk sharing as it's quite slow and will adversely effect processing. ------------------------------ Trevor R.H.
