Hi,

I have downloaded the Eigen-2.0-beta1 library and have included it with visual studio 2005. I am trying to find the Eigenvector of a matrix by using the function eigenvectors() but I am getting the following error.

error C2039: 'eigenvectors' : is not a member of 'Eigen::Matrix'
1> with
1> [
1> _Scalar=double,
1> _Rows=3,
1> _Cols=3
1> ]

I am able to find the eigenvalues for that matrix by using eigenvalues().

Please let me know where am I goin wrong?
Thanks a lot.

You seem to be trying to call eigenvectors() as a method of Eigen::Matrix, which does not have such a method, so the compiler tells you about it.

I think you are looking for EigenSolver

Yah your right. Do you know any method by which I can get the eigenvectors?[/align]

From the API docs I'd say you'll need to create an instance of an Eigen::EigenSolver using the same template specialization you used for the matrix and pass the matrix to its constructor.

Then you can call eigenvectors() on this new instance.

ok. Thanks a lot..
