Hello, I have a problem when applying Useparallel in genetic algorithms. This is my code:

    i
  ObjFcn = @myFitness;
  IntCon=[1 2 3 4 5];
  nvars = 5;
  LB= [lb1 lb2 lb3 lb4 lb5];
  UB= [20 100 100 100 100];
  ConsFcn= @Repecarga;
  opts = gaoptimset('PlotFcns',{@gaplotbestf,@gaplotbestindiv},'UseParallel',true);
  opts.PopulationSize = 30;
  [ho,fval]=ga(ObjFcn,nvars,[],[],[],[],LB,UB,ConsFcn,IntCon,opts)

My objective function is as follows:

    i
  function y = myFitness(ho)
  y = 65*ho(1)+15*ho(2)+13*ho(3)+ 7*ho(4)+2*ho(5)
  end

The error I get is this

Error in ga (line 351)
    [x,fval,exitFlag,output,population,scores] = gaminlp(FitnessFcn,nvars, ...
Error in EJECUTABLE (line 136)
[ho, fval]=ga(ObjFcn,nvars,[],[],[],[],LB,UB,ConsFcn,IntCon,opts)
Caused by:
    Failure in user-supplied fitness function evaluation. Cannot continue.
    Failure in initial user-supplied fitness function evaluation. GA cannot continue.

Regards.

Sorry. This is the complete error that appears. Attachments bring the complete code, the file "EJECUTABLE" is the one that starts the algorithm.

Error using Repecarga (line 33) Subscripted assignment dimension mismatch.
