Having problems with my function code iterating an initial guess (optimization)

Question

Hello people,

Im having problems trying to iterate from an initial guess.

On my function file i got a function FRes

function R=FRes(guess,~,~,~,~,~)
R=(1./(Tk.^alpha-g))-((beta*alpha*g.^(alpha-1))./((g.^alpha)-gg));

Where my guess is included in the "g" and the "gg" variable.

So i created this code trying to optimize:

It=@(guess)FRes(guess,alpha,beta); (which i think says, on the FRes function the thing u gonna change is "guess".

Then I try doing fminsearch/fzero on (It,guess) on (FRes,guess) on (R,guess) but im not having any luck.

Thanks in advance for your time.

Sorry, I do not understand what you are asking.

Perhaps you can include your entire function call, such as

x = fzero(fcn1,x0)

and also include the MATLAB output. Then perhaps I will understand.
