Synthesize signal from cosine packet coefficients
x = IPT_CP(btree,coef,D,bell) Paraameters Inputs: btree: basis tree selecting Cosine Packet basis coef : coefficients in that basis D : maximum splitting depth bell : name of orthonormal bell Outputs: x : 1-d signal whose cosine packet coeff's in basis btree come from cp
Perform the inverse operation of FPT_CP.
