CHORDSOL Chord method code for scalar equations.

This code terminates on small relative-absolute errors, function [X, HIST] = CHORDSOL(X, F, TOLA, TOLR)



Inputs: X = initial iterate

F = function

TOLA = absolute error tolerance

TOLR = relative error tolerance



Output: x=approximate result-CHORDSOL　Chord method code for scalar equations.
