[Insight-users] how can I use the newmat C++ library for matrix operations

[Luis Ibanez]

Hi Seniha,

ITK class names will not collide with class names from
other libraries because ITK uses the "itk::" namespace.

You can combine ITK with other C++ libraries that have
classes with the same name as ITK classes.

In any case...
note that ITK *already* has a Matrix library. This is
VNL from VXL. You should look at the Matrix operations
available in VNL:

         Insight/Utilities/vxl/core/vnl

It is likely that they already offer all what you need.


    Regards,


       Luis
