I’m having trouble figuring out: How to do a broadcast vector subtraction from a matrix using the C++ lib Eigen?

When I try something like this:

  Vector3d mean;
  mean << 2, 3, -1;

  MatrixXd pts(5, 3);
  pts << 0, 0, 0,
         1, 0, 0,
         0, 1, 0,
         0, 0, 1,
         1, 1, 0;

  MatrixXd results(5, 3);
  results = pts.colwise() - mean;

I get the following result:

-2.00000 -2.00000 -2.00000
-2.00000 -3.00000 -3.00000
1.00000 2.00000 1.00000
-2.00000 -2.00000 ovf
-3.00000 -3.00000 0.00000

What am I doing wrong? Thanks!
