This can be accomplished with the following code for an interval (a, b) whose output is a multidimensional matrix of size m x n x p ….

The uniform distribution is commonly used to generate random numbers over an interval. The function rand generates pseudorandom numbers with a uniform distribution over the range of (0, 1). In this section, we will give a brief overview of each of these functions. The basic suite of random-number-generating functions includes rand, randn, randi, and randperm. Matlab has the capability of producing pseudorandom numbers for use in numerical computing applications. In this post, I will explain the basic random number generation commands in Matlab, including rand, randn, randi, and randperm, and provide some example applications.

This will include the usage of the basic commands, how to control random number generation, how to create other distributions from the basic functions that Matlab provides, and what alternatives there are to the functions used in Matlab. % % draw samples from a population of amino acids (i.e.In this series of posts, I will explain how to use the various random number generation functions in Matlab.
