Dear David, Wayne, Paul
thanks for your replies.
Well, that's exactly what I feared: no way out!
Just to show you how common the problem is one can try:
utplot,[1,2,3],[1,2,3],0
mpfit
or, if you don't have utplot,
.comp
function limits
end
mpfit
Even if utplot might not be as widespread as mpfit,I guess there are
quite a few people around using both of them...
Dear Craig,
should you ever feel like giving up idl 4, I think you could be
surprised how many people might volunteer to help you translating
some code to []-notation!
Greetings,
Paolo
