FSOLVE requires at least two input arguments.

I am trying to run a scipt I from File Exchange, but I am getting error "Error using fsolve (line 186) FSOLVE requires at least two input arguments" Can please help fix the error?

% Prepare the options for the solver

options = prepareOptionsForSolver(options, 'fsolve');

end

if nargin == 0

error(message('optim:fsolve:NotEnoughInputs')) (line 186)

Please share the code you are running that is causing this error.

The first person to ask is the author who submitted it to the file exchange. Since there are thousands of submissions, you should link to the one you're using and post the code you're using to call it.
