How can I use STL containers in my C++ shared library?

I would like to implement STL containers with my C++ shared library project, for example the STL vector, with the mwArray API. I want to do this for performance reasons.

You can use an STL container by copying it to a standard C++ array and then using the mwArray API. Below is an example of using a STL vector with the mwArray API.

#include "mclcppclass.h"

#include <vector>

int main(int argc, int **argv)

{

if (!mclInitializeApplication(NULL,0))

{ std::cerr << "could not initialize the library properly"<<std::endl;

return 1;

} 

std::vector<double> B;

int arraysize;

int* A;

//use dynamic array allocation

A = new int[arraysize];

int a =2;

int b=-5;

//populate the vector

B.push_back(a);

B.push_back(b);

//copy the vector components to the dynamic array

std::copy(B.begin(), B.end(), A);

mwArray Y(2,1, mxDOUBLE_CLASS);

Y.SetData(A,2);

std::cout << Y << std::endl;

delete[] A;

B.clear();

return 0;

}

Then build the project in MATLAB

mbuild -v TestExample.cpp

!TestExample.exe
