Not only is it desirable to have sparse and full matrices behave similarly,

is used so functions like eig() would work for either.
The key is to use the C++ class system to have different implementations
for each storage format.

I haven't been following this thread closely and I haven't thought much about the details but I have no objection to trying to do a better job with handling numel and dimensions/indices generally.

Is there some way we can get the better behavior in a minimally invasive way?

Even if it requires significant changes, maybe we should consider what the options are anyway.

What changes are needed to make octave_idx_type behave the way you way you want?
