I have tried to use the submatrix method for initializing a 10 x 5 matrix N from the first columns and rows of the 10 x 10 matrix M.
I am probably missing something, since it seems that N is not assigned the expected values of M (all ones). Any suggestions?
#include <iostream> #include <string> #include "gurls++/gvec.h" #include "gurls++/gmat2d.h" using namespace gurls; using namespace std; typedef double T; int main() { gMat2D<T> M(gMat2D<T>::zeros(10,10)+1); cout << "M initialized: " << endl << M << endl; gMat2D<T> N(gMat2D<T>::zeros(10,5)); // Initialize N M.submatrix(N , 10 , 5); cout << "N initialized: " << endl << N << endl; }
Output:

Thank you.
