This would be really nice to have. I tried recently to use the unsupported matrix power, and ran into a number of segfaults for very simple matrix powers:
#include <iostream>
#include <unsupported/Eigen/MatrixFunctions>
int main()
{
Eigen::MatrixXcd A(2,2);
A << 1, 1, 4, -2;
// Segfaults:
//Eigen::MatrixPower<Eigen::MatrixXcd> Apow(A);
//std::cout << Apow(3.1) << "\n\n";
// Segfaults:
//std::cout << A.pow(3.1) << "\n\n";
// Segfaults:
//std::cout << A.pow(3.1).eval() << "\n\n";
// Segfaults:
//Eigen::MatrixXcd B(2,2);
//B = A.pow(3.1);
}
I use matrix power a lot, it would be nice if this worked in Eigen.
Actually this entry is about coefficient-wise power, see the function signatures.
