Hi,

I am trying to understand how to set maximum size arrays threshold in case of a Simulink model that needs to use Matlab functions that support variable size arrays.

Is "Maximum stack size (bytes)" the proper parameter to set? I am asking this since I have to generate a C code for my model for an embedded application and I need to be sure to set an upper threshold for all the variables inside my model.

Hi Francesco,

I understand that you want to set an upper threshold on the size of the code generated for all the variable-sized arrays in a MATLAB Function Block in Simulink.

Instead of using the "Maximum stack size (bytes)" parameter, you can control the use of dynamic memory allocation for the variable-sized arrays. Please refer to the following documentations for more information on the same:
