Detailed Description

template<class T>
class vnl_matrix_ref< T >

vnl_matrix reference to user-supplied storage. vnl_matrix_ref is a vnl_matrix for which the data space has been supplied externally. This is useful for two main tasks: (a) Treating some row-based "C" matrix as a vnl_matrix in order to perform vnl_matrix operations on it. (b) Declaring a vnl_matrix that uses stack-based storage for the matrix (See MatrixFixed). Note however that the rows are still allocated on the heap. See MatrixFixed for a fully stack-based solution.

This is a dangerous class. I believe that I've covered all the bases, but it's really only intended for interfacing with the Fortran routines.

The big warning is that returning a vnl_matrix_ref pointer will free non-heap memory if deleted through a vnl_matrix pointer. This should be very difficult though, as vnl_matrix_ref objects may not be constructed using operator new, and are therefore unlikely to be the unwitting subject of an operator delete.
