Thomas Neidhart commented on MATH-1143:
---------------------------------------
What helper methods do you have in mind?
For example to get the first / second order derivative of a univariate function?
> Helper methods to FiniteDifferencesDifferentiator
> -------------------------------------------------

> Key: MATH-1143
> URL: https://issues.apache.org/jira/browse/MATH-1143
> Project: Commons Math
> Issue Type: Improvement
> Reporter: Alexander Nozik
> Priority: Trivial
>
> A DerivativeStructure and UnivariateDifferentiableFunction are great tools if
> one needs to investigate the whole function but are not convenient if one
> just needs derivative in a given point.
> Perhaps you could add some helper methods to FiniteDifferencesDifferentiator
> or to utility class like FunctionUtils. Also it would be good to have helper
> methods to get the derivatives of UnivariateDifferentiableFunction or
> MultivariateDifferentiableFunction as simple Univariate or Multivariate
> functions (or vector-functions).
