## Build special first/last database for some wavelet density functions

### Description

This function builds a special first/last database for some of the wavelet density estimation functions written by David Herrick and described in his PhD thesis.

See `first.last` to see what this kind of function does.

### Usage

    first.last.dh(LengthH, DataLength, type = "wavelet", bc = "periodic",
        firstk = c(0, DataLength - 1))

### Arguments

`LengthH` | The length of the smoothing (C) filter
`DataLength` | The length of the data that you wish to transform
`type` | The type of wavelet transform, `wavelet` or `station` for decimated and nondecimated transforms respectively.
`bc` | Boundary conditions, `periodic` or `symmetric`
`firstk` | The first k index, leave as default

### Details

Description says all.

### Value

A list with several components in exactly the same format as for `first.last`.
