Morning,

When running my model, I receive the following message " Error using ==> trustnlegn , Ojective funtion is returning undefined values at initial point. FSOLVE cannot continue."

I am a beginer so I need some advices to solve this problem.

THKS.

When I run it in Dynare 4.3.2 it clearly shows the problem. You did not provide initial values. Hence, Dynare uses 0. But your first equation says for example

Hence, if C is initialized to 0, you start with an NaN.

Thatâ€™s why Dynare says

[quote]Please check for example

i) if all parameters occurring in these equations are defined

ii) that no division by an endogenous variable initialized to 0 occurs[/quote]
