Ok then maybe I'm confusing things, the operations that I want to see giving
NaN values for sparse matrices where appropriate and sparse matrices if the
sparse_auto_mutate flag isn't set are
speye(3)/0
speye(3).^0
speye(3)* NaN
etc. Yes the last two are still giving odd behavior and you probably aren't
repsonsible.. I'll look at it when I'm back at home..
