While running my genetic algorithm code i'm getting the following errors

Attempt to reference field of non-structure array.
Error in setwb (line 23)
inputLearn = net.hint.inputLearn;
Error in rmse_test (line 17)
net = setwb(net,x');
Error in @(x)rmse_test(x,{net,inputs,targets})

Error in genetic_algorithm (line 55)
[x_ga_opt, err_ga] = ga(h, 3, ga_opts);
Caused by:
    Failure in user-supplied fitness function evaluation. GA cannot continue.
