%FRAMETF2COEF  Convert coefficients from TF-plane format
%   Usage: cout=frametf2coef(F,cin);
%
%   FRAMETF2COEF(F,cin) converts the frame coefficients from the
%   time-frequency plane layout into the common column format.
%
%   Not all types of frames support this coefficient conversion. The supported 
%   types of frames are: 'dgt', 'dgtreal', 'dwilt', 'wmdct', 'ufilterbank',
%   'ufwt','uwfbt' and 'uwpfbt'.
