[Insight-users] itk::VariableSizeMatrix

[Julien Michel]

Dear ITK users,

We are using the itk::VariableSizeMatrix class when our matrix size can 
not be decided at compilation time.

In this class encapsulating the vnl/vnl_matrix class redefines all the 
operators, such as += or -= for instance.

In these operators, a size check is performed in order to check the 
matrices compatibility. Eventually, an exception is raised using the 
itkExpectionMacro. This macro needs the GetNameOfClass method to be defined.

However, the VariableSizeMatrix derives from nothing, and no 
itkTypeMacro is used in its header, so there is no GetNameOfClass method.

This lead us to compiling errors whenever we are trying to use these 
operators.

To fix this, I think either an itkTypeMacro should be used in the class 
declaration or an itkGenericExceptionMacro should be used in the 
operators checking.

Best regards,

Julien Michel
