biorfilt - bi-orthogonal spline 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);
