function r = ratioa(c)
 
% The function RATIOA calculates the local non-orthogonal leakage for pair of adjoining components,
% where r is calculated according to the following rule
% being applied to the case when c is the 2-D array.
%	r(i)= | c(i)*c(j) | / (c(i)^2 + c(j)^2), i=1,k j=1,k 
%	and k is the number of IMF components.
%
% Calling sequence-
% r=ratioa(c)
%
% Input-
%	c	- 2-D matrix c(n,k) of IMF components
%		 excluding the trend component.
% Output-
%	r	- vector r(k) of the ratio for adjoining components
%		- r(i) = | (c(1,i)*c(1,j)+...+c(n,i)*c(n,j)) | /
%			( c(1,i)^2+c(1,j)^2+...+c(n,i)^2+c(n,j)^2 )
