% function accepts 1 double and 2 vectors of double 
%		a611(#num_of_points, vector_a, vector_b)
% number of datapoints in both vectors must be equal, 
% or else the result will not be correct

%exp.:
%	a=[0, 5, 10, 15, 20 ]
%	b=[1, 0.8811, 0.7366, 0.5430, 0.1698]
%	[a1,a2,a3,a4,a5]=a611(5,a,b)
%	a1 = -0.023780
%	a2 = -0.026340
%	a3 = -0.033810
%	a4 = -0.019360
