Fsolve can't continue

[killergabin]

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

Code: Select all

1/C

Hence, if C is initialized to 0, you start with an NaN.
That's why Dynare says

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
