While using fminsearch I am getting the following error
Maximum number of function evaluations has been exceeded
- increase MaxFunEvals option.
Current function value: NaN
I am trying to maximise an utility function.
I will provide the code below.
function [utility] = demo(a,initx,b,q,nyears,alpha,beta,discount)
%define output variable x
%b = 0.42;
%initx = 0.0;
%q =2;
%alpha = 0.4
%beta = 0.08;
%discount = 0.98;
%nyears =100;
x = Lakemodel(initx,b,q,a,nyears);
v = zeros(nyears,1);
% Code for Lakemodel you can run it as a different function
%function [x,source,sink] = Lakemodel(initx,b,q,a,nyears)
%define output variable x
%x = zeros(nyears,1);
%x(1) = initx;
%for t = 2 : nyears%
%x(t) = x(t-1) + (a(t-1)) - b*x(t-1) + x(t-1)^q/(x(t-1))^q+1;
%end
%end
for t = 1:nyears
v(t) = discount^t*(alpha*a(t)-beta*x(t)*x(t));
end
utility = sum(v(:,1));
utility = utility*-1;
