wmpdictionary
(To be removed) Dictionary for matching pursuit
wmpdictionary
will be removed in a future release. Use sensingDictionary
instead. For more information, see Compatibility Considerations.
Syntax
Description
[
returns the row vector, MPDICT
,NBVECT
]
= wmpdictionary(N
)NBVECT
, which contains the number of
vectors in each subdictionary. The order of the elements in
NBVECT
corresponds to the order of the subdictionaries and
any prepended or appended subdictionaries. The sum of the elements in
NBVECT
is the column dimension of
MPDICT
.
[
returns the dictionary, MPDICT
,NBVECT
]=
wmpdictionary(N
,Name,Value
)MPDICT
, using additional options
specified by one or more Name,Value
pair arguments.
[
returns the cell array, MPDICT
,NBVECT
,LST
]
= wmpdictionary(N
,Name,Value
)LST
, with descriptions of the
subdictionaries.
[
returns the cell array, MPDICT
,NBVECT
,LST
,LONGS
]
= wmpdictionary(N
,Name,Value
)LONGS
, containing the number of vectors
in each subdictionary. LONGS
is only useful for wavelet
subdictionaries. In wavelet subdictionaries, the corresponding element in
LONGS
gives the number of scaling functions at the coarsest
level and wavelet functions by level.
