Hello everyone!

Im just getting started into eigen and trying to run the first example found here:

http://eigen.tuxfamily.org/dox-devel/classEigen_1_1EigenSolver.html

However im getting error messages cause the compiler cant find the classes MatrixXd, VectorXcd, MatrixXcd, MatrixXcd and EigenSolver even when im including Eigen/Core. For the Eigensolver class I read in the documentation that including Eigen/Eigenvalues is needed, but it doesnt exist in the /Eigen directory.

I downloaded the version 2.0.15 from the eigen main page.

Could someone tell me please how to make it work?

Thanks in advance

You are using version 2 of Eigen, but this documentation is about the developer version (version 3).
Probably you did not specify

Code: Select all

using namespace Eigen;

in your code.

Ah...i was using the wrong version ._.

Its working now

thx
