Gamultiobj with double summation help

[funyhony]

how can i use gamultiobj or ga, I've input of (i, j) matrix and i want (i,j) output

i've equation to solve with ga

f = sumation from i to class[ sumation from j to rows(yij * log(pij)))]
how to solve with ga


fun f = funGa1(Pij,Yij,class,rows)

f = - symsum(symsum(Yij*log(Pij),i,1,Class-1),j,1,rows)


and in other file

f = @(Pij)funGa1(Pij,Yij,Class,rows)

% 0 =< Pij <= 1
lb = 0;
ub = 1;

options = gaoptimset('PopulationSize',rows*class,'Generations',1000, ...
'Vectorized','on','PlotFcns',@gaplotpareto);
[x fval] = gamultiobj(f,class,[],[],[],[],lb,ub,options)

i've many many errors
like :

1- mtimes Inner matrix dimensions must agree
2- ? Error using ==> mtimes
Inner matrix dimensions must agree.

3- Error in ==> validate>@(x)fitness(x,FitnessFcnArgs{:})
at 136
fitness = @(x) fitness(x,FitnessFcnArgs{:});

and much more

please tell me what i can do

It looks like there is a problem with your code. It is difficult to tell what exactly is wrong without seeing the full code. You may need to review your code and make sure that all of the parameters you are passing in to the gamultiobj function are valid. Additionally, you should ensure that the variables you are using in your objective function (f) are correctly defined and that all of the matrix dimensions are compatible. Once you have reviewed your code and made sure that everything is correctly specified, you can try debugging the code to find out exactly where the error is coming from.
