I have matrix 1x16. I will reshape this matrix to 4x4. How can I reshape this matrix? I just use this code, but the program was break.

//transpose 
    Mat det0 = Mat(d1);
    Mat dt1;
    dt1 = det0.reshape(0,4);
    cout << " Sebelum transpose "<<det0 <<endl;
    cout << "coba" << dt1 <<endl;

Mat square(const Mat &in)
{
    size_t n = in.total(); //count of all elements
    size_t ns = (size_t)sqrt(double(n));   // squared
    CV_Assert(ns*ns == n); //make sure, there was no rounding.
    return  in.reshape(0, ns);
}
