function x = FastS2(c, n, NameOfDict, par1, par2, par3)
% FastS2 -- the SYNTHESIS operator for a dictionary:
%			x = \Phi * c
%  Usage:
%	x = FastLS2(c, n, NameOfDict, par1, par2, par3)
%  Inputs:
% 	c		the coefs, a structure array
%	NameOfDict	name of the dictionary
%	par1,par2,par3	the parameters of the dictionary
%
%	Use 'help dictionary' for dictionary objects: NameOfDict,par1,par2,par3
%  Outputs:
%	x		the synthesized image, a n by n matrix
