# frnd

F random numbers

## Syntax

```R = frnd(V1,V2) R = frnd(V1,V2,m,n,...) R = frnd(V1,V2,[m,n,...]) ```

## Description

`R = frnd(V1,V2)` generates random numbers from the F distribution with numerator degrees of freedom `V1` and denominator degrees of freedom `V2`. `V1` and `V2` can be vectors, matrices, or multidimensional arrays that all have the same size. A scalar input for `V1` or `V2` is expanded to a constant array with the same dimensions as the other input. `V1` and `V2` parameters must contain real positive values.

`R = frnd(V1,V2,m,n,...)` or `R = frnd(V1,V2,[m,n,...])` generates an `m`-by-`n`-by-... array containing random numbers from the F distribution with parameters `V1` and `V2`. `V1` and `V2` can each be scalars or arrays of the same size as `R`.

## Examples

```n1 = frnd(1:6,1:6) n1 = 0.0022 0.3121 3.0528 0.3189 0.2715 0.9539 n2 = frnd(2,2,[2 3]) n2 = 0.3186 0.9727 3.0268 0.2052 148.5816 0.2191 n3 = frnd([1 2 3;4 5 6],1,2,3) n3 = 0.6233 0.2322 31.5458 2.5848 0.2121 4.4955```
