It would appear to me that the difficulties that the Matlab users are having is with the use of the Matlab is learning how to use the Matlab functions correctly. In the small code snippett given by mahdi ahmadi there are functions used that seem to not be be parameterized correctly. Click the following links for more info on some of these functions:

    serial()

    fopen()

    fscanf()

    fclose()

    delete()

To program it really does require to know how the functions work.
