function [Ke]=bar1e(ep);
% Ke=bar1e(ep)
%-------------------------------------------------------------
% PURPOSE
%  Compute element stiffness matrix
%  for spring (analog) element.
%
% INPUT:  ep = [k];       spring stiffness or analog quantity.
%
% OUTPUT: Ke :            stiffness matrix, dim(Ke)= 2 x 2
