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);
