NewtonRaphson

class NewtonRaphson extends AnyRef

This class is used to find roots (zeros) for a one-dimensional (scalar) function f. If f is the derivative of some other function g, then this technique can be used to find optima for g. Caveat: Use Conjugate Gradient or Quasi-Newton for complex optimizations.
