dwt
Discrete wavelet transform (1D)
Calling Sequence
[U, V] = dwt(X, WNAME)
[U, V] = dwt(X, HP, GP)
[U, V] = dwt(X, HP, GP,...)
Parameters
Inputs:
X:
Signal Vector.
WNAME:
Wavelet name.
HP:
Coefficients of low-pass decomposition FIR filter.
GP:
Coefficients of high-pass decomposition FIR filter.
Outputs:
U:
Signal vector of average, approximation.
V:
Signal vector of difference, detail.
