I have a dense matrix A (100x100) and I want to extract a matrix B from it consisting of the first N columns of A. Is there a better way to do it than getting the column using MatGetColumnVector, followed by VecGetArray, and MatSetValues? It could also be done using MatGetSubMatrix but is seems to be more involved. <div>
