Name
biorfilt — bi-orthogonal wavelet filter set
Calling Sequence
[Lo_D,Hi_D,Lo_R,Hi_R]=biorfilt(DF,RF)
Parameters
- DF
-
: analysis scaling filter
- RF
-
: synthesis scaling filter
- Lo_D
-
: lowpass analysis filter
- Hi_D
-
: highpass analysis filter
- Lo_R
-
: lowpass synthesis filter
- Hi_R
-
: highpass synthesis filter
Description
orthfilt is an utility function for obtaining analysis and
synthesis filter set of given bi-orthogonal spline wavelets. DF and
RF should be output of biorfilt result with the same length.
Examples
[RF,DF]=biorwavf('bior3.3');
[lo_d,hi_d,lo_r,hi_r]=biorfilt(DF,RF);
