It depends on what arrays you mean. DOUBLE arrays can be saved in binary files easily. If you are talking of struct arrays, which fields contain handles of graphic objects, the problem is serious.

You can either write a Mex function to call the C++ routine directly without the indirection over the hard disk. Or you can save the data to a binary file using fopen/fwrite/fclose.

Hi Mohammed,
There are a few different ways to achieve this as Jan mentioned. I would also suggest a few other ways:
- Using MATLAB Engine APIs to interface with C++ code: https://www.mathworks.com/help/matlab/matlab_external/pass-variables-from-matlab-to-c.html
- Using coder.ceval to call C++ code and passing arguments via coder.rref: https://www.mathworks.com/help/simulink/slref/coder.rref.html
I hope this helps!
