function f=tfr_sr(self,c,Ls)
%TFR_SR  Synthesis transform, rectangular layout
%  Usage: f=tfr_sr(tfr,c)
%         f=tfr_sr(tfr,c,Ls)
%
%   Input parameters:
%         tfr   : Time/frequency representation handle.
%         c     : Array of coefficients.
%         Ls    : length of signal.
%   Output parameters:
%         f     : Signal.
%
%   TFR_SR(tfr,c) computes the synthesis transform of the coefficients c as
%   speficied by tfr. The coefficients must be arranged in a rectangular
%   layout as returned by TFR_AR.
%
%   TFR_SR(tfr,c,Ls) does as above but cuts or extends f to length Ls.
%
%   SEE ALSO:  TFR_CREATE, TFR_AR, TFR_A, TFR_CLEAR
