function f = trf2(X,V,E);
%> This file calculates the transfer matrix for 1D Schroedinger DE
%> for an interval with a linear potential 
%> Call: trf2(x,V,E) 
%> Input: X=[x1, x2] is the interval as a row 2-vector, x1 < x2
%> V = potential values at endpoints =[V(x1), V(x2)];
%> E = energy lattice, row vector
%> Output: a column 4-vector [u;Du;v;Dv] of values at x2
%> where (u,v) are the fundamental solutions defined by
%> u(x1) = Dv(x1) = 1, Du(x1) = v(x1) = 0.
