Support of Haar Wavelet
Return the lower bound and upper bound of the support for the Haar wavelet.
[LB,UB] = wavsupport('haar')
LB = -0.5000
UB = 0.5000
The length of the Haar wavelet filter is 2. Compare
UB to the lower and upper bounds for orthogonal and biorthogonal wavelets (type 1 and type 2).
LF = 2; LowerBound = -0.5*(LF-1)
LowerBound = -0.5000
UpperBound = 0.5*(LF-1)
UpperBound = 0.5000
Support of Complex-Valued Gaussian Wavelet
Return the lower bound and upper bound of the support for the complex-valued Gaussian wavelet.
[LB,UB] = wavsupport("cgau3")
LB = -5
UB = 5
LB,UB — Wavelet support
Wavelet support, returned as scalars.
UB are the lower and upper bounds, respectively, of
For real-valued wavelets with and without scaling functions and complex-valued wavelets without scaling functions (wavelets type 3,4, and 5), the bounds indicate the effective support of the wavelet.
For orthogonal and biorthogonal wavelets (type 1 and type 2 respectively), the lower and upper bounds are
LB = -0.5*(LF-1)and
UB = 0.5*(LF-1), where LF is the length of the wavelet filter.
B — Support of the wavelet
Support of the wavelet, returned as a vector:
