There is a code that I am trying to improve by eliminating the global variables. The only issue is is that the function that is used for fminsearch has other functions inside that need the global variables. So I am thinking of passing a structure through fminsearch with an anonymous function. However, when I run the new code it seams like fminsearch is not performing properly becuase it goes at double the speed and not return a good answer.
Here is the original code calling the fminsearch function:
[p,c] = fminsearch('cost',p0);
function [c,meanErr] = cost(p)
global PHIs TAUs Parameters
Instead of having the variables of PHIs, TAUs, and Parameters as global, I send them to a structure S. Here is how I am trying to pass the structure through fminsearch:
[p,c] = fminsearch(@(p) costLeg(S), S.p);
function [c,meanErr] = costLeg(S)
Am I passing this structure correctly? How can I double check that I am?
Thanks!
