{
  // Better would be if the Mat type allows easy swapping of rows...
  result.resize(B.numRows(),
                B.numColumns());  // leaves B alone if correct size already...
  for (long r = 0; r < B.numRows(); r++)
    for (long c = 0; c < B.numColumns(); c++)
      B.ring().set(result.entry(r, c), B.entry(permutation[r], c));
