This code gives a compile error: ``` Eigen::MatrixXd M(3,3); // defined elsewhere Eigen::MatrixXd M_inv; double det(0); bool invertible(false); M.computeInverseAndDetWithCheck(M_inv, det, invertible); ``` but the following does not, and only gives an exception at runtime ``` Eigen::Matrix3d M; // fixed size 3x3 matrix Eigen::MatrixXd M_inv; // dynamic matrix <-- this should fail at compile time, or resize to 3x3 double det(0); bool invertible(false); M.computeInverseAndDetWithCheck(M_inv, det, invertible); ``` I expected the second bit of code to give another compile time error, or the dynamic matrix to be re-sized to 3x3 by the `computeInverseAndDetWithCheck` function.
