A: This is a known problem of versions 2.XX, a conflict between MARCH and Matlab 7.x. It has been solved in version 3.00. If you are still using an older version of MARCH, you can use the following method: The problem lies in the Path environment variable of your system. Go to your system path variable (start/settings/control panel/system/advanced/environment variables). You probably have one element corresponding to Matlab and one corresponding to March. Modify the line to make sure that the element corresponding to March is located BEFORE the one corresponding to Matlab.
