# Math::GSL::DHT(3pm)

Discrete Hankel Transforms

\_\_END\_\_

## NAME

Math::GSL::DHT - Discrete Hankel Transforms

## SYNOPSIS

```
    use Math::GSL::DHT qw/:all/;
```

## DESCRIPTION

Here is a list of all the functions included in this module :

- gsl\_dht\_alloc($size) - This function allocates a Discrete Hankel transform object of size $size.

  - "gsl\_dht\_new($size, $nu, $xmax)" - This function allocates a Discrete Hankel transform object of size $size and initializes it for the given values of $nu and $xmax.

  - "gsl\_dht\_init($t, $nu, $xmax)" - This function initializes the transform $t for the given values of $nu and $xmax.

  - "gsl\_dht\_x\_sample($t, $n)" - This function returns the value of the $n-th sample point in the unit interval, (j\_{\\nu,n+1}/j\_{\\nu,M}) X. These are the points where the function f(t) is assumed to be sampled.

  - "gsl\_dht\_k\_sample($t, $n)" - This function returns the value of the $n-th sample point in "k-space", j\_{\\nu,n+1}/X.

  - gsl\_dht\_free($t) - This function frees the transform $t.

  - "gsl\_dht\_apply"
