Matlab error: Error using simulannealbnd Too many input arguments. Error in mainsa (line 12) [x, fval, exitflag, output] = simulannealbnd(abc, x0, [], [], lb, ub, options);

clc;
clear all;
close all;
abc = @function1;
x0 = 0;
lb = 0;
ub = 0.7;
options = saoptimset('OutputFcns',@outputfunction)
[x, fval, exitflag, output] = simulannealbnd(abc, x0, [], [], lb, ub, options);

While running the above code it shows some error:

Error using simulannealbnd

Too many input arguments.

Error in mainsa (line 12)

[x, fval, exitflag, output] = simulannealbnd(abc, x0, [], [], lb, ub, options);

How can I solve this?

Hi ASWATHI,

The correct syntax for the 'simulannealbnd' function is as follows: "simulannealbnd(fun,x0,lb,ub,options)". Based on your code, it seems that you are passing an extra argument in your function call. To resolve this issue, you should modify your function call from:

%Existing function call
[x, fval, exitflag, output] = simulannealbnd(abc, x0, [], [], lb, ub, options);
%Modified function call 
[x, fval, exitflag, output] = simulannealbnd(abc, x0, lb, ub, options);

This adjustment removes the extra argument, aligning the call with the expected syntax and should solve the issue.
