Hello all! In my program code i have such random variables,they change for each iteration.Also there is some functions are depending on.These functions will generate results. In order to compare 3 approaches , i should use same results so i want to ask you if it is possible to save results for "100 iterations" and still use them for different approaches. hope that all clear, Thanks in advance.

perhaps use rng() to set the random number seed so they use the same random numbers?

Yes, I want to generate 100 different random variables and save them in specific matrices so I can use these variables for all scenarios in order to compare them using same values.

Yes you can do it. Whether it is a good idea to handle the situation this way is a different question.

rng(12345);
NumIter = 100;
MatrixSize = [73 19];
for iter = 1 : NumIter
    data = rand(MatrixSize);
    filename = sprintf('Matrix%03d', iter);
    save(filename, 'data');
end
