Matching Pursuit using Cosine Packet Dictionary with backfitting
atomic = CPPursuitBF(x,D,bell,natom,frac,show)
1-d signal to be decomposed
maximum number of atoms desired
min fraction total signal energy to enter
usual Cosine Packets parameters (Depth, name of bell)
plot intermediate results? 0=no, 1=yes
parameters of atomic decomposition [a l b k]
norm of residules from each step
If show=1, intermediate results are plotted
