# Handling DWT Coefficients

Convenience routines are available for converting the outputs of the multilevel dwt functions (`wavedec`, `wavedec2` and `wavedecn`) to and from a single, concatenated coefficient array.

## Concatenating all coefficients into a single n-d array

## Splitting concatenated coefficient array back into its components

## Raveling and unraveling coefficients to/from a 1D array

## Multilevel: Total size of all coefficients - `wavedecn_size`

## Multilevel: n-d coefficient shapes - `wavedecn_shapes`
