biorwavf - bi-orthogonal spline wavelets scaling filter
biorwavf is an utility function for obtaining twin scaling filters of bi-orthogonal spline wavelet including bior1.1, bior1.3, bior1.5, bior2.2, bior2.4, bior2.6, bior2.8, bior3.1, bior3.3, bior3.5, bior3.7 and bior3.9. Although the twin filters have different length, zeros has been fed to keep two filters the same length.
[RF,DF]=biorwavf('bior3.3');
