function [x,a]=hilbertnormalize(x,r)

% The function HILBERTNORMALIZE normalizes data using its own Hilbert transformation.
% 
% Non MATLAB Library function used is: HILBTM
% First argument is required. If not passed, second argument defaults to 0.
% If flipping of data is desired r should be set to 1.
%
% Calling sequence-
% [x,a]=hilbertnormalize(x[,r])
%
% Input-
%	x	- 2-D input data x(m,n)
%	r	- flipping mode 
% Output-
%	x	- 2-D normalized data
%	a	- 2-D Hilbert envelope
%
% Used by-
% 	FA
