Name

wavefun2 — 2-D Wavelet and Scaling Functions

Calling Sequence

[S,W1,W2,W3,XYVAL]=wavefun2(wname,ITER)

Parameters

wname
: wavelet name
ITER
: iteration cycle, default is 4, large cycle may consume more time
S
: tensor product of PHI and PHI
W1
: tensor product of PHI and PSI
W2
: tensor product of PSI and PHI
W3
: tensor product of PSI and PSI
XYVAL
: 2-D time domain grid

Description

wavefun2 is an utility to get 2-D scaling function phi and wavelet function psi. Only available on orthogonal wavelets. ITER should be small integers for short computation time.

Examples

[S,W1,W2,W3,XYVAL]=wavefun2('sym4',4);
