[Insight-developers] FEM Registration : dsrc2c.c : Copyrights

[Luis Ibanez]

Hi Jim, Nick,


As you probably saw in the mailing list,
we have recently removed the file


    Insight/Code/Numerics/FEM/dsrc2c.c


because it is copyrighted by IMSL and we
do not have a license for distributing
the code.

One of the consequences of this removal
is that the classes

   itkFEMItpackSparseMatrix
   itkFEMLinearSystemWrapperItpack

were removed as well.

These two classes where used in the

   itkFEMRegistrationFilter


as replacement, we use now the ITK wrapper
over the VNL linear system solver. However,
this one is not as efficient as the previous
one.


We are wondering if you are aware of other
efficient linear solver for sparse matrices
for which we could get the source with a
license compatible the the BSD-like license
used by ITK.

We will appreciate any hints,


   Thanks


      Luis
