newton.rb

Solves the nonlinear algebraic equation system f = 0 by Newton's method. This program is not dependent on BigDecimal-

To call:

  n = nlsolve(f,x)
where n is the number of iterations required,
      x is the initial value vector
      f is an Object which is used to compute the values of the equations to be solved-

It must provide the following methods:

f.values(x)

returns the values of all functions at x

f.zero

returns 0.0

f.one

returns 1.0

f.two

return
