Function: frsyn
FRSYN  Frame synthesis operator
  Usage: f=frsyn(F,c);

  f=FRSYN(F,c) constructs a signal f from the frame coefficients c*
  using the frame F. The frame object F must have been created using
  FRAME.

  Examples:
  ---------

  In the following example a signal f is constructed through the frame
  synthesis operator using a Gabor frame. The coefficients associated with 
  this Gabor expansion are contained in an identity matrix. The identity 
  matrix corresponds to a diagonal in the time-frequency plane, that is, 
  one atom at each time position with increasing frequency.:

     a = 10;
     M = 40;

     F = frame('dgt', 'gauss', a, M);

     c = framenative2coef(F, eye(40));

     f = frsyn(F, c);
