Feb 18, 2018 · rand() effectively generates an integer in the range [0, 2^53-1], retries if the result was 0, and then divides the integer now in the range [1, 2^53-1] by 2^53 to give the random value. It is not possible to get higher precision than that over any range that starts above 1 .

This example discusses the steps to generate and visualize random numbers and vectors that are drawn from univariate, bivariate, and trivariate normal distributions. The randn function generates random numbers from the standard normal distribution.

This example shows how to create an array of random floating-point numbers that are drawn from a uniform distribution in the open interval (50, 100).

Generate a 5-by-5 matrix of uniformly distributed random numbers between 0 and 1.

There are four fundamental random number functions: rand, randi, randn, and randperm. The rand function returns floating-point numbers between 0 and 1 that are drawn from a uniform distribution. For example, create a 1000-by-1 column vector containing real floating-point numbers drawn from a uniform distribution.

Mar 22, 2012 · Learn more about random number generator, matlab function I need to create a value for one of my variables in a loop which will run ten times. I need it to be between two set values, e.g. 1e3 and 9e3.

Use the new syntax rng(generator) to specify the algorithm for the random number generator to use. This syntax allows you to set the random number algorithm without specifying the seed, where rng uses a seed of 0. This syntax is equivalent to rng(0,generator).

Random Integers. This example shows how to create an array of random integer values that are drawn from a discrete uniform distribution on the set of numbers –10, –9,...,9, 10. The simplest randi syntax returns double-precision integer values between 1 and a specified value, imax.

This MATLAB function generates a random number from the normal distribution with mean parameter mu and standard deviation parameter sigma.

This MATLAB function returns a random number from the one-parameter distribution family specified by name and the distribution parameter A.
