WFILT_LEMARIE Battle and Lemarie filters
Usage: [h,g,a]=wfilt_lemarie(N)
Input parameters:
N : Filter length, must be even.
[h,g,a]=WFILT_LEMARIE(N) calculates N (even) truncated coeficients
of orthonormal Battle-Lemarie wavelets. Filter coefficients are obtained
by frequency domain sampling and trunctating the impulse response.
Due to the truncation, the filterbank might not achieve a perfect
reconstruction. The filetrs are included nevertheless since they were
the original ones used in the first MRA paper.
Examples:
---------
:
wfiltinfo('lemarie50');
