[h,g,a]=wfilt_lemarie(N)
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.
