MATLAB: How to avoid fitness function issue in quadratic equation problem of genetic algorithm tool

genetic algorithmindexoptimizationquadratic equation

I was trying to use genetic algorithm tool of matlab for the fitness function
function totR = objFcn(in1)
%OBJFCN
%    TOTR = OBJFCN(IN1)
%    This function was generated by the Symbolic Math Toolbox version 5.8.
%    22-Mar-2012 09:47:17
x1 = in1(1,:);
x2 = in1(2,:);
x3 = in1(3,:);
x4 = in1(4,:);
x5 = in1(5,:);
x6 = in1(6,:);
.......
The ga command:
[x1, fval1] = ga(@objFcn,2*N,A,b,Aeq,beq,LB,UB,[],options);
It is showing the error:
??? Attempted to access in1(2,:); index out of bounds because size(in1)=[1,100].
Error in ==> objFcn at 9
x2 = in1(2,:);
Would anybody help me in this issue? I would appreciate it.

Best Answer

[x1, fval1] = ga(@(x) objFcn(x .'), 2*N, A, b, Aeq, beq, LB, UB, [], options);
