[X,cA,cDe] = wpsplt(T,N)
also returns the approximation and detail coefficients cA and
cDe, respectively, of the node. For this syntax,
T is a 1-D wavelet packet decomposition.
[X,cA,cH,cV,cD] = wpsplt(T,N)
also returns the horizontal, vertical and diagonal detail coefficients
cH, cV, and cD,
respectively, of the node. For this syntax, T is a 2-D wavelet
packet decomposition.
Approximation coefficients of a node, returned as a vector or matrix. For
a 1-D decomposition, cA is a vector. For a 2-D
decomposition, cA is a matrix.
cDe — 1-D detail coefficients vector
Detail coefficients of a node in a 1-D wavelet packet decomposition,
returned as a vector.
cH,cV,cD — 2-D detail coefficients matrices
Detail coefficients of a node in a 2-D wavelet packet decomposition,
returned as matrices. cH, cV, and
cD correspond to the horizontal, vertical, and
diagonal details, respectively.
