Hi,
I use the genetic algorithm-ANN codes for classification. I share you part of my codes.
h= @(x)mse_test(x,net, P, Output);
ga_opt = gaoptimset('display','iter', 'TolFun', 1e-8, 'CrossoverFraction', cr, ...);
[x_ga_opt, final_err_ga, exfl, ouput] = ga(h,10*n+1,ga_opt);
I only can get the final_err_ga value. Bu also confusion matrix(conf) is calculated in ga tool but I cant see it in result screen end of the run. How can I extract the conf variable?
function cal = mse_test(x,net, P, Output)
....
cal=(1/Accuracy);
conf = confusionmat (Output, z);
end
I can share screenshot if necessary. Thank you very much.

I think that the easiest way would be to run everything in a nested function, as in this example.

The nested function allows access to all variable values that you want. Simply pull the values into the main function from the nested functions. See Nested Functions.

Hi again,
I couldn't get through my problem. Cause I'm not competent at using Matlab I suppose. Could you help me if I upload my all codes in here? My problem is to exract last conf (variable) value from mse_test function.
I would be very grateful if you help. My files are included in the appendix.
