[vtkusers] Numerical Analysis / Optimization lib + VTK ? (conjugate gradient) ?

[Sebastien BARRE]

Hi users,

Is someone aware of any free Numerical Analysis library that might be 
used/linked with VTK on a Windows platform ?

I mean something that *you* have really tested, where calls to the 
numerical API could be used right within VTK classes.

Ease of use and efficiency would be nice :)

I'd like to use stuff like Multidimensional Conjugate Gradient Methods (ok, 
it's optimization), and do not want to reimplement the wheel :)

Thanks a lot.
