 Yeah - big issue for us too.

 [ ... examples of different ways to compare matrices snipped ... ]
 And yup to all of those.

 Even worse, we occasionally have even more interesting mathematical
 beasties --- "states" (e.g. vector + covariance matrix) and
 probability distributions --- to compare.

 What I'm poking at right now is a generic way to

      A) teach mathematical objects how to compare themselves in
      various ways


      B) have that work smoothly with the Boost Test stuff.

 I don't have a good solution yet... but gimme another day or two. :-)
