In the above function, 'p' is a vector and 's' as well. I have to pass the vector 'p' to a c++ program to compute 's'. The above function is called several times. My idea is to first write the vector 'p' in a file, which the c++ program reads in. The c++ program writes its output 's' also in a file, which MATLAB can read in.

WebThis is an implementation of a container much like std::vector. It is meant to be used when the size is expected to be reasonably small.
