Did you read the error message? You need a toolbox that is either not installed, or not available for you to check out.

Hi Subrata,

It is clearly mention in your error that Optimization Toolbox is not installed in this version of your MATLAB.

You may look into this link for how you can install additional toolboxes.

Hope this Helps!
