Hi all,
GluCat ( http://glucat.sf.net ) defines operator== for multivectors.
For matrix_multi this is implemented by: 
1) check the matrices to see if either has zero entries
2) if so, subtract and use norm_inf
3) if no, iterate over both matrices in lock step, comparing entries.
Best regards, Paul Leopardi
