If you get an "Out of memory" message the most likely reason is not that the computer is running out of memory, but that you have asked it to do something silly which requires zero memory, so check this first. If you get an "Out of stack memory" message then it may be that you are asking the program to perform an especially complicated calculation, though to be honest we don't think that this is likely to happen. However should it occur first check that you have not made a mistake and then try to simplify what you are asking the program to do, perhaps by doing it in stages.
