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);
