Hi,
I'm new to Matlab mex. I'm trying to write a mex function which in turn will take the structure data from a .cpp file and use it in matlab.
I came to know that plhs and prhs are the pointers to an array which hold the output data and input data respectively, each element of type mxArray.
Since structure size can be large, Is there any maximum size limit for the plhs and prhs array to hold the data ? If so, What are the alternate ways?

The maximum size limit is 2^48-1 elements per variable and 2^48-1 variables for input or output.

Needless to say, you will probably run out of memory before you hit these limits.
