[Insight-developers] itk::Matrix initialized when execution problem

[Arnaud Gelas]

Hi Nicolas,

The size of the matrix for an itk::Matrix needs to be fixed, and  
declared as const unsigned.

For instance, you can declare an itk::Matrix
const unsigned int nrow = 4;
const unsigned int ncol = 5;
itk::Matrix< float, nrow, ncol > distance;

If you want to change the dimension of the matrix at run time, you  
should probably have a look at vnl_matrix

HTH,
Arnaud
