Undefined function 'ga' for input arguments of type 'function_handle'.

Hi,

I have 2014a version of matlab on my mac. I am trying to solve a MILP using ga. The global optimization toolbox is installed on my system, and I also have the license for it. But when I try to run the ga, I get the following error:

Undefined function 'ga' for input arguments of type 'function_handle'.

A snippet from my code:

fn = @(x) f'*x;

[x,fval,exitflag]=ga(fn,2*n^2,A,b,Aeq,beq,lb,ub,[],intcon);

I don't know how to debug it, since documentations says that I need to supply a function handle here.

Try entering

 which -all ga

Perhaps there is another ga file that is getting precedence.

Even better, use intlinprog rather than ga for much better performance and reliability.
