Creating a surface plot using Simulink?

Hi everyone! I have a quite simple thing to do....

I have a Subsystem in Simulink with one output which calculates something from two inputs, so y = f(u,v).

All I wanna do is feed the block with two vectors, e.g. u = [0:.01:2] and v = [60:120]. I want my subsystem to calculate all results for all possible combinations and store it to a matrix in the workspace. I would like to create a surface plot with the result in the end. So there's no differential calculation or anything time-dependent in my subsystem.

I know how to do all this in MatLab but in that case I would have to recreate the whole content of my subsystem as a MatLab script.... Alternatively, does anyone know how to to export a Simulink subsystem to MatLab code? That would do the trick too I guess...

Thansk in advance Volker

Hi Vokler, if you already have designed the simulink model, you could simply use load_system and sim to get the output.

There are a few different approaches to this. I described one in this post . That one's most suited for animating MATLAB graphics with Simulink, but you might find it useful.
