Why this error happened when i run genetic algorithm?

when i run this function in genetic algorithm in optimization tool box this error occur

• Attempt to execute SCRIPT ga as a function:

    function [ F ] = FF( A )

It sounds likely that you have a different file ga.m which is being found by MATLAB first.

If you type:

which ga

you will be returned the file which MATLAB is trying to execute. If this is the correct version from the Global Optimization toolbox, it would be found in matlabroot\toolbox\globaloptim\globaloptim\ga.m. You then would need to remane the file or place it lower on the MATLAB Search Path .

[Firas Al-Kharabsheh]

how to do this ????

[Walter Roberson]

Firas, what is returned when you use

which ga

[Firas Al-Kharabsheh]

i see this C:\Users\Haitham Khlifat\Documents\MATLAB\ga.m

[Brendan Hamm]

Exactly, this is not the function which comes with the Toolbox. Go to that location and change the name of that file to something else.

Presumably if you type

which ga -all

you will find the location I mention beneath this on the list. This means that MATLAB will find your files in the Documents directory before it finds files provied with your toolboxes.

Type:

rmpath('C:\Users\Haitham Khlifat\Documents\MATLAB\ga.m')
addpath('C:\Users\Haitham Khlifat\Documents\MATLAB\ga.m','-end')

and this will make it find your files last. Read that link I posted above so you can understand how MATLAB searches for files.
