... Sorry that didn't post.
Ok, once again. This goes in the "why doesn't it work like i think it
Suppose I have an expression which, for the sake of argument, looks
exp((-1.)*(0.0 + Gauss1(x,p(0:2)) + Gauss1(x,p(3:5))))
where gauss1 is another function (of x) and p is a set of input
I want to evaluate this function, but can't seem to do it with either
call_function or execute. I've tried:
model='exp((-1.)*(0.0 + Gauss1(x,p(0:2)) + Gauss1(x,p(3:5))))'
expstring='model=exp((-1.)*(0.0 + Gauss1(x,p(0:2)) + Gauss1(x,p(3:5))))'
to no effect... What am i missing about call_function or execute? Do all
the elements of the evaluated function need to be IDL native? Does the
conversion of a string to a function make anyone else uneasy?
Thanks for any help! - Dirk
