Hello please can someone help me out with this. My model stopped running with the following errors. I have attached a copy of my matlab code to serve as a guide. I got some results for all my unknown variables but they were all negative which is not suppose to be, as there are no negative quantities or goods.

Solver stopped prematurely.
fsolve stopped because it exceeded the function evaluation limit,
options.MaxFunctionEvaluations = 2.000000e+04.

Hi,
I understand that you are trying to use the 'fsolve' function to solve your system of equations and the model stopped as it has exceeded the function evaluation limit.
This has happened because 'fsolve' has exceeded the maximum number of function evaluations allowed, which, in your code, was set as 20000, using the function 'optimset'. You can change it by specifying the value of 'MaxFunEvals' in the code. You can learn about the different optimization options that you can set using the 'optimset' function in the following Documentation link :
For trouble shooting the issue, you can refer to the following link :
