[Insight-developers] itk::array< itk::vector > - broken?

[Lydia Ng]

I think I had a similar problem before due to itk::Vector not being one =
of
the standard types already instantiated in the vnl library - you might =
need
to include vnl/vnl_vector.txx to get an itk::Array (a.k.a) vnl_vector of
itk::Vector.=20
