The best way to export opencv data and import in matlab

edit

So I've a question as from title. But I want underline that I will want avoid the mex-file but only use the binary file or xml file. My question in particular is related to export the points tracked with calcOpticalFlowPyrLK and relative error. Up to now, I used the following code but I don't know if it's correct way

outfile.open("file.bin", ios::out | ios::binary);
outfile << status.size() << endl; 
for( int i=0; i < status.size(); i++ )
{       
    if( !status[i] )
        outfile<< 0 << endl;
    else
        outfile << 1 <<endl;

}
outfile << points1 << endl;
outfile << points2<< endl;

stringstream ss (stringstream::in | stringstream::out); 
for(int i=0; i < err.size(); ++i)
{
   ss << err[i] << endl;
}
outfile << ss.str(); 
outfile.close();

where points1 and point2 are the features points tracked by LK algorithm in first frame and second frame respectively. Can you help me?
