Restore the state of the random number generator to s, and then create a new random number. handle to another function. This object contains the estimated parameter values, mu and sigma, for the fitted normal distribution. Random Number Generation Seeds, distributions, algorithms Use the rand, randn, and randi functions to create sequences of pseudorandom numbers, and the randperm function to create a vector of randomly permuted integers. You can also select a web site from the following list: Select the China site (in Chinese or English) for best site performance. You can then specified distribution parameters. rng function to control the repeatability of your results. The Probability Distribution Function user the array sizes must be the same. Do you want to open this example with your edits? PS: You forgot to add the 0 on this line -> x = sum(rand >= cumsum([0.5, 0.1, 0.4)); Now that I think about it, my comment is out of place.
