## RANDNF Generate Noncentral F-Distribution Random Variable

Section: Random Number Generation

### Usage

Generates a vector of non-central F-distributed random variables with the specified parameters. The general syntax for its use isy = randnf(n,m,c)

where `n`

is the number of degrees of freedom in the numerator,
and `m`

is the number of degrees of freedom in the denominator.
The vector `c`

determines the non-centrality shift of the numerator.

### Function Internals

A non-central F-distributed random variable is the ratio of a non-central chi-square random variable and a central chi-square random variable, i.e.,

### Example

Here we use the`randf`

to generate some non-central F-distributed
random variables:
--> randnf(5*ones(1,9),7,1.34) ans = Columns 1 to 8 1.9422 0.5987 0.1890 0.7468 2.3759 8.2553 1.8047 0.2222 Columns 9 to 9 2.2680
