Hi all.
I am using MATLAB in my COMSOL model. After defining all the input variables in the .m file and saving it in the same directory with the .mph file, the simulation shows no error but i don't know how i can access and use the output variable from the .m file?
e.g. function[Ax]=permtty(tx, kx, lam0) .....how can i retrieve and use "Ax" in the COMSOL model?

Hope anyone can help.

Hi

Is the function permtty something you wish to evaluate while solving?

Then look in the manual "Introduction to LiveLink for Matlab" in this chapter "Using External MATLAB® Functions" for a way to call the function from COMSOL Multiphysics.
