SymmetricMatrix provides no memory savings for dense formats #104

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
The SymmetricMatrix is only a decorated around existing matrices.  If one wants 
to use a dense format, the Symmetric matrix will still require the full N^2 
memory storage since the backing matrix would still create all the potential 
space used.  For dense matrices, this shouldn't be a decorator, it should just 
be it's own implementation that guarantees 1/2 memory usage.
