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);
