# iwsst

Inverse wavelet synchrosqueezed transform

## Syntax

## Description

returns the inverse wavelet synchrosqueezed transform of `xrec`

= iwsst(`sst`

)`sst`

.
The `iwsst`

function assumes that you obtained
`sst`

using the `wsst`

function with default
parameters.

**Note**

The wavelet synchrosqueezed transform does not preserve the signal mean. After inverting the synchrosqueezed transform, you must add the original signal mean.

The inverse wavelet synchrosqueezed transform is an approximate inverse which is not guaranteed to provide perfect reconstruction.

returns the inverse wavelet synchrosqueezed transform with additional options
specified by one or more name-value arguments.`xrec`

= iwsst(___,`Name=Value`

)
