I'm trying to generate C code for a function but one of the parameters is an MxN matrix, so I'm not sure how to call the function in the single line the wizard gives me to call it. I tried myfunc([ [1 2] [2 3] ], 1.0 ,1.0, 1.0). It didn't like that, so I tried myfunc([ [1 2] ; [2 3] ], 1.0 ,1.0, 1.0) and then it started complaining one of the other parameters shold be a scalar. Are those not all scalars?

You do not necessarily write everything in one line. Just write a script (as long as you want) that calls that function and make sure it runs without any error. Then type the name of that script on this line in Code generator GUI. It will automatically infer the size and type of the variables.

Oh, looks like it doesn't. I'm trying to gen the code for a matlab function and figured matlab's own code would compile so didn't test it. I guess I'll have to try getting the matlab code to compile.

I think it is not possible to generate the code of MATLAB built-in function directly. You will need to call it in your own function to generate the code.
