Hello everyone! :)
I am trying to generate a random number according to a probability distribution that I create. Let me explain:
I have a matrix p (2 * n): p : row 1: 1 2 3 4 5   row 2: 0.1 0.1 0.6 0.2 0
I want to get a number randomly according to the distribution p (2, :) to be able to 1,2,3,4 or 5.
Do you know of a function that can do this in matlab?
Thank you very much

Check out the datasample function, including its 'Weights' argument.
