Dear sirs
i have problem with this code . can any one help me
Index exceeds matrix dimensions.
Error in Untitled3 (line 47)
CTI1 = A(1,1)*x(1)+A(1,6)*x(6)
the code
%To minimize our fitness function using the ga function, we need to pass in a function
% handle to the fitness function as well as specifying the number of variables as the
% second argument. Lower and upper bounds are provided as LB and UB respectively. In
% addition, we also need to pass in a function handle to the nonlinear constraint function.

I've reproduced the error. The problem is that the variable, x, is empty when executions arrives at the line
CTI1 = A(1,1)*x(1)+A(1,6)*x(6)
