Cast Eigen::MatrixXd to Eigen::MatrixXf

Question

I am using Eigen on a C++ program.

I wonder if there is a way to cast from Eigen::MatrixXd to Eigen::MatrixXf .
static_cast <Eigen::MatrixXf> doesn't seem to work and neither A.cast<MatrixXf> (this is the cast method from Eigen).

Any solution for this type of cast?

Answer 1

Try this:

Eigen::MatrixXd d;                       // Matrix of doubles.
Eigen::MatrixXf f = d.cast <float> ();   // Matrix of floats.
