Writing GPU Array Type: Which Array Class to Inherit From?

[David Bateman]

Wouldn't it be better to inherit from octave_matrix and store a copy of 
the matrix in the original octave_matrix::matrix value and the version 
in GPU memory in the new class and synchronize the two values as 
needed.. You won't inherit the operators at the octave prompt if you 
inherit directly for a liboctave class.
