function data= ReadGrasshopperFile( ~, ~,~)
x = randi(10, 1);
y = randi(10, 1);
z = randi(10, 1);
parameters = [x, y, z];
fileName1='M2GHfileName.csv';
fileName2='GH2Matlab.csv';
writematrix(parameters, fileName1);
data = readmatrix(fileName2);
end

This function that I defined it works good.

But, I wanted the x and y and z changed each time that I recall function.

what should I do?

I don't understand what you are trying to do, but I repeat:

The optimization toolbox cannot cope with random inputs that change with iteration.

So you can create random input, but it must remain constant during the optimization process.

I wanted to creat a function that gives ne random number and save these variable in csv file, after a sleep time read other csv file. I dont want to use optimization toolbox; I use a swarm optimization.
