[ITK-users] Assigning to VariableSizeMatrix

[DVigneault]

All--

I'm getting a segmentation fault upon attempting to assign to an
itk::VariableSizeMatrix.  I tried to find an example of its usage in the
doxygen, wiki, and software manual, but didn't see one.  Here's a minimal
example of my problem:

#include "itkVariableSizeMatrix.h"

int main( int argc, char * argv[] )
{
	
	if( argc != 1 )
    {
        std::cerr << "Usage: " << argv[0] << std::endl;
        return EXIT_FAILURE;
    }
    
    typedef itk::VariableSizeMatrix< double > MatrixType;

	MatrixType matrix;
	matrix(0,0) = 1.0; // Segmentation fault: 11

  return EXIT_SUCCESS;
  
}

Can anyone point out my mistake, or point me toward an example?

Best, and thanks,

--Davis
