# haart

Haar 1-D wavelet transform

## Description

`[`

performs the 1-D Haar discrete wavelet transform of the even-length vector,
`a`

,`d`

] =
haart(`x`

)`x`

. The input `x`

can be univariate or multivariate
data. If `x`

is a matrix, `haart`

operates on each
column of `x`

. If the length of `x`

is a power of 2,
the Haar transform is obtained down to level `log2(length(x))`

. Otherwise,
the Haar transform is obtained down to level
`floor(log2(length(x)/2))`

.

`[`

specifies how the Haar transform handles integer-valued data, using any of the
previous syntaxes.`a`

,`d`

] =
haart(___,`integerflag`

)
