axis('equal') should work like matlab's option. Your post suggests
that your version does and I infer therefore that the current
axis('equal') does not. I'm wondering if we should substitute your
version in there. Even if not, we can do both, with a suitably named
flag. Would you be willing to incorporate your suggestion into the
axis function and submit it as a patch to the sf site?

Sounds good.
