Generating C code for Simulink model with .mat

Hi,

I have a Simulink model that loads its parameters from a .MAT file by means of an init-function (Model Properties - Model Callbacks - Init function):
load('modeldata.mat');


Now I would like to generate a C code of this model by means of Real Time Workshop, but I am always getting an error "Undefined variable modeldata" .

Does anybody know how to generate a C code for a Simulink model that needs to load a .mat file before running?


regards,
Adrian

Model (and block) callback routines are executed by the MATLAB engine and are not part of the simulation loop (which is essentially what gets converted to C code with Simulink Coder/RTW).

But you can use the RSIM target to execute a model while getting its parameters from a .mat file.
