In probability theory and statistics, the discrete uniform distribution is a symmetric probability distribution wherein a finite number of values are equally likely to be observed; every one of n values has equal probability 1/ n. The function gendist (P,N,M) takes in a positive vector P whose values form a discrete probability distribution for the indices of P. The function outputs an N x M matrix of integers corresponding to the indices of P chosen at random from the given underlying distribution. R_scalar = unidrnd (100) R_scalar = 82. Remember that a random variable is just a quantity whose future outcomes are not known with certainty. r = unidrnd(n) generates
