=========================
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.
.. currentmodule:: pywt
Concatenating all coefficients into a single n-d array
------------------------------------------------------
.. autofunction:: coeffs_to_array
Splitting concatenated coefficient array back into its components
-----------------------------------------------------------------
.. autofunction:: array_to_coeffs
Raveling and unraveling coefficients to/from a 1D array
-------------------------------------------------------
.. autofunction:: ravel_coeffs
.. autofunction:: unravel_coeffs
Multilevel: Total size of all coefficients - ``wavedecn_size``
--------------------------------------------------------------
.. autofunction:: wavedecn_size
Multilevel: n-d coefficient shapes - ``wavedecn_shapes``
--------------------------------------------------------
.. autofunction:: wavedecn_shapes
