How to build atoms from the book [ Reply ]

Hello all;

I use MPTK in Matlab. everything has been worked fine but I want have as output a matrix of NxM such that N is the number of samples of atom and M is the number of atoms in the book. Following of this equation: sigrecons = sum( Coef(i) x atom(i)); Ceof(i) is the inner product between risiduel and the best atom ( i.e atom(i)).

I extracted Coef(i) by Coefs=sqrt(decay(1:end-1)-decay(2:end));
and for each Coef(i) I search in the book the correspond atom, but i cann't build atoms correctly and thus the sigrecons hasn't the same curve w.r.t original signal curve.

Can any one help me please?
