[Insight-developers] about class Vector

[Luis Ibanez]

Hi,

The declaration of th itk::Vector class should work fine.

You're right, you should be able to assign values to
any component of the vector (this is inherited from
itk::Array).

One possibility is that you're using this with a type
(T) which is 'const', for example Vector<const char,3>
will prevent you from assigning values to the components.

Could you please post a more complete piece of code ?
or at least the complete error message that you get
along with the platform in which this is being tested ?

It looks like the problem should be comming from the 
surrounding code.

Thanks

Luis
