I want to write a maple program/script involving matrix computations. The program will consist of approximently 50 statements and will require user supplied input data. I have Maple 9 and would like to call the script from Matlab. Matlab would provide the input data to the Maple script and then I would like to have Maple pass the output data to Matlab. Is there a way to do this using Maple 9 or do I need the new Maple Matlab toolbox? Thank you, Richard
