define the local variable in Function to global
显示 更早的评论
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?

At the moment you are writing one file but reading a different file.
You could create random data, or you could use random numbers to modify the file you read, or if you have several files to read from you could read one at random.

At the end of the function before the end statement add
data = data + randi(10, size(data)) ;

"I wanted when I run file it gives me a new number and results." - but this does happen already: randi replies random integers. As long as you do not reset the random number generator manually before, you get new values.

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.
