There is no command for doing that out of the box, but it is nevertheless feasible with some programming.
There are several ways of doing that that you could try:
- load your MAT file from your MOD file, and repeatedly use the "set_param_value" command
- alternatively, write a MATLAB program which creates a text file containing the parameter assignations, and include that generated file from the top-level MOD file using the "@#include" macro-processor command
