Hi

I am wondering if it is possible to assign a vector to a row of a matrix?

============ main.d ==========
import mir.ndslice;

void main() {

  auto matrix = slice!double(3, 4);
  matrix[] = 0;
  matrix.diagonal[] = 1;

  auto row = matrix[0];
  row[3] = 4;
  assert(matrix[0, 3] == 4);

  // assign it to rows of a matrix?
  auto vector = sliced!(double)([10, 11, 12, 13]);

// ??? Here I would like to assign the vector to the last (but it is not working)

  // matrix[2] = vector;
}
============

So I am wondering what the correct way is to do such an assignment without looping?

matrix[2][] = vector;

Or

matrix[2,0..$] = vector;
