Building MEX file error: struct exceeding 2GB

I am trying to convert my matlab code to c++ using MATLAB coder, but I am getting an error saying "...size of 'struct defined at c:\user... _type.h (linenumber)' exceeds 2147483647 bytes" during the step of building MEX.

I am using Window 10, 64bit. My code handles 3D images and a lot of FFTs. I use 'clear' in my matlab code to free up the memory, but 'clear' is not supported by data generation.

Is there a way to fix this error?

Thanks!
