Efficient way of loading a big structure in a simulink model toward a real time application

I have a large struct ~ 100 mb which stores a bunch of multidimensional arrays. The struct is read inside a matlab function in my simulink model.

I’m wondering what’s the best way to load that kind of struct into matlab function? Using Coder.load or defining it as a parameter of the matlab function?

I’m using coder.load but my model generates an error saying ‘out of heap space’ during compilation. I suspect this error is somehow related to my way of loading/reading this struct.

The exact error is as follows:

Fatal error c1060 : compiler is out of heap space. Nmake : fatal error u1077. The make command returned an error of 2.

I’m using slrt.tlc, as I’ll be using simulink real-time to run my model.
