It looks like triangularView doesn't support multiplication by scalars
(except in-place). Is this just an oversight, or is there some reason
implementation would be difficult?
To be precise, the following does not compile:
#include <Eigen/Core>
int main() {
Eigen::MatrixXd m1(5, 5);
m1.setRandom();
Eigen::MatrixXd m2(5, 5);
m2 = m1.triangularView<Eigen::Upper>() * 3.0;
}
Thanks!
