Dyadic table of all Cosine Packet Coefficients
cp = CPAnalysis(x,D,bell)
1-d signal: length(x)=2^J
depth of finest time splitting
name of bell to use, defaults to 'Sine'
1-d packet table (n by D+1).
The table cp contains coefficients of all Local Cosine Decompositions. The Local Cosine Transform for time interval [b/2^d,(b+1)/2^d] is stored in cp(packet(d,b,n),d+1).
