Hi all,

I am trying to create a one voxel image (that will grow depending on the number of steps in the algorithm) using to following code:
    const unsigned int Dimension = 3;
    typedef itk::Matrix<double, 4, 4> MatrixType;
    typedef itk::Image<MatrixType, Dimension> MatrixFieldType;
    MatrixFieldType::Pointer matrixfield = MatrixFieldType::New();
    MatrixFieldType::IndexType index;
    index.Fill( 0 );
    MatrixFieldType::SizeType size;
    size.Fill( 1 );
    MatrixFieldType::RegionType region( index, size );
    matrixfield->SetRegions( region );
    MatrixType matrix;
    matrixfield->SetPixel( index, matrix );
However this code crashes.
When I fill size with 2's, the code seems to work.

Any ideas? Maarten
