Question: Biorthogonal Splines in Ten Lectures

Dear Wavelet Enthusiasts:

I have evaluated the expressions for m0(xi) for the bi-orthogonal spline
basis/filters on page 271 in Daubechies' Ten Lectures on Wavelets. The filter
coefficients from those two formulas do not match the coefficients for (N~,N)M0
given on the right hand side of Table 8.2 on page 277 in most of the cases. The
coefficients from page 271 are symmetric and add up to unity, as do the
corresponding cases in Table 8.2.

Am I evaluating something wrong, or is there a typo somewhere? Have any
of you out there encountered the same problem, or have an answer? I would
greatly appreciate it if someone can shed some light on this.

Thanks a lot in advance
