Hello everyone.
While using GlobalSearch in my global optimization routine, I incountered the following error:
Error using globalsearchnlp (line 110)
All elements of X must be real.
Im not able to open this file, "globalsearchnlp". What are these X? How can I fix it?
Many thanks!

Try
dbstop if error
before you execute your global search. It'll stop in the debugger then, maybe that'll enable you to find out what's wrong.

Your function evaluations are sometimes producing imaginary numbers. Be sure to put in appropriate bounds on your function range.

Yes, thank you. I found the place where my code produced complex numbers.
