Dear all,

I want to import the f(x,y) function computed in MATLAB into COMSOL, I don't know which function to use The data I got with MATLAB is discretized, the variables x,y are 601x1 matrices, f(x,y) is the 601x601 matrix, I don't know which function to use to import this three-dimensional discrete data into COMSOL. Best regards！

The function shape is in the file.

...and if you want to do it from the GUI, use Interpolation Functions. They have been discussed many time in this Discussion Forum.
