Wavelet filters

bl(n) Returns the Battle-Lemarie wavelet based upon the degree n cardinal B-spline. n is an integer between 0 and 6, inclusive.

Bspline(m,n) Returns the analysis and synthesis low-pass filters for a spline-based biorthogonal wavelet. When m = 1, n is 1, 3, or 5. When m = 2, n is 2, 4, 6 or 8. When m = 3, n is 1, 3, 5, 7, or 9.

coiflet(n) Returns the low-pass filter of the n-coefficient Coiflet wavelet. n is 6, 12, 18, 24, or 30.

daublet(n) Returns the low-pass filter of the n-coefficient minimum phase Daubechies wavelet. n is an even integer between 2 and 20, inclusive.

symmlet(n) Returns the smoothing filter of the n-coefficient least asymmetric Daubechies wavelet. n is an even integer between 4 and 20, inclusive.
