This is an advanced feature for experienced C programmers. MATLAB automatically
converts data passed to and from external library functions to the
data type expected by the external function. Use a
instead of automatic conversion in the following situations.
You want to modify the data in the input arguments.
You are passing large amounts of data, and you want to control when MATLAB makes copies of the data.
The library stores and uses the pointer for a period
of time so you want the MATLAB function to control the lifetime
