# normrnd

Normal random numbers

## Syntax

```R = normrnd(mu,sigma)R = normrnd(mu,sigma,m,n,...)R = normrnd(mu,sigma,[m,n,...])```

## Description

`R = normrnd(mu,sigma)` generates random numbers from the normal distribution with mean parameter `mu` and standard deviation parameter `sigma`. `mu` and `sigma` can be vectors, matrices, or multidimensional arrays that have the same size, which is also the size of `R`. A scalar input for `mu` or `sigma` is expanded to a constant array with the same dimensions as the other input.

`R = normrnd(mu,sigma,m,n,...)` or ```R = normrnd(mu,sigma,[m,n,...])``` generates an `m`-by-`n`-by-... array. The `mu`, `sigma` parameters can each be scalars or arrays of the same size as `R`.

## Examples

```n1 = normrnd(1:6,1./(1:6)) n1 = 2.1650 2.3134 3.0250 4.0879 4.8607 6.2827 n2 = normrnd(0,1,[1 5]) n2 = 0.0591 1.7971 0.2641 0.8717 -1.4462 n3 = normrnd([1 2 3;4 5 6],0.1,2,3) n3 = 0.9299 1.9361 2.9640 4.1246 5.0577 5.9864```
