Wavelet decomposition vector, specified as a vector.
C contains the approximation and detail
coefficients organized by level. The bookkeeping matrix
S is used to parse C. For more
information, see wavedec2.
Example: [C,S] = wavedec2(X,3,"db4") returns the level 4
wavelet decomposition of X using the
db4 wavelet.
Data Types: double
Bookkeeping matrix, specified as an integer-valued matrix. The matrix
S contains the dimensions of the wavelet
coefficients by level and is used to parse the wavelet decomposition vector
C. For more information, see wavedec2.
Percentage of energy corresponding to the approximation, returned as a
scalar.
Data Types: double
Percentage of energy corresponding to the horizontal, vertical, and
diagonal details, respectively, returned as 1-by-L
vectors, where L is the level of the wavelet
decomposition. The kth element of the vector is the
percentage of energy at the kth level.

EDetail is the sum of the vectors
Eh, Ev, and
Ed.
