Hello! I want my 50 inputs to take a random value from a set of numbers (already defined) with an equal probability..

These 50 inputs will be undefined. Those will take a random value from [0 0.1 0.2 0.3 0.4 0.5] with an equal probability. So in the end these 50 will have values from [0 0.1 0.2 0.3 0.4 0.5] selected randomly with equal probability. This can be done with a nested for loop. Can you please explain how?

I don't see why you'd want to use a loop.

value_set = [0, 0.1, 0.2, 0.3, 0.4, 0.5];
numvalues = 50;

random_selection = value_set(randi(numel(value_set), 1, numvalues))  %select numvalues out of value_set with uniform probability.

It works! :) Now I have a martix of [1*50] elements, which are randomly chosen. But is it taking care of choosing with the numbers with an equal probability?

[Guillaume]

Yes, as documented randi selects numbers uniformly. You can easily check by changing numvalues to a large number and plotting the histogram of the selected values.

It works. Thanks a lot! :)
