[vtkusers] How to get Eigen values and Eigen vectors ?

[Kiran, P (CORP, GEITC)]

Hi all:

I want to do eigen decompostion for a matrix (of order 3x3) to extract the
principal axes.
I have looked at   vtkMath::Jacobi(....,....,...); But it works only for a
symetrical matrix ( of order 3x3).

Does anyone tried for eigen decomposition for a general matrix ( of order
3x3) ?
Are there any available methods on vtk to do this stuff.

Thanks in advance for help..
