Max_in_place is a sample MEX file that shows a generic framework for multi-threaded processing in MEX functions.

Syntax: max_in_place(matrix1, matrix2)

The 2 input matrices must be real non-sparse and have the same number of elements. The matrix1 input is updated in-place (without memory reallocation) with the maximal value of corresponding elements in the two matrices.

Multi-threading is controlled via Matlab's builtin maxNumCompThreads function.
The code can easily be adapted for other processing types.
