[ADMB Users] Opposite of mfexp()

[Mark Payne]

Hi,

I seem to have struck a problem with some code that I've narrowed down to the folllowing.The problem is essentially that

nll -= tmpl;

and

nll -= log(mfexp(tmpl));

(where nll is my objective function and tmpl is a temporary dvariable)

lead to different results in the optimisation - the first one sensible, and the second one not. Am I doing something outstandingly silly here? Or is there something that I haven't understood?
