function c = FastA(x, NameOfDict, par1, par2, par3)
% FastA -- the ANALYSIS operator for a dictionary:
%			c = \Phi^T * x
%  Usage:
%	c = FastA(x, NameOfDict, par1, par2, par3)
%  Inputs:
% 	x		the signal, a column vector
%	NameOfDict	name of the dictionary
%	par1,par2,par3	the parameters of the dictionary
%
%	Use 'help dictionary' for dictionary objects: NameOfDict,par1,par2,par3
%  Outputs:
%	c		the coefs, a column vector
%  See Also:
%	FastAA, FastS, FastSS, MakeList
