------------------------------------

             Summary: Minor design suggestions for RealVector and MultivariateDifferentiableFunction
                 Key: MATH-998
                 URL: https://issues.apache.org/jira/browse/MATH-998
             Project: Commons Math
          Issue Type: Wish
    Affects Versions: 3.2, 3.1
            Reporter: Alexander Nozik
            Priority: Minor


I am working on some kind of data analysis framework and using Math as a platform. There are
some minor inconveniences in the architecture wich i want to note.
The first problem concerning RealVector clas. It has a lot of features (too much from my point
of view) but does not implements any simple interface. Also it is not connected with geometry
package wich is not a problem in my case, but seems strange.
The second problem is MultivariateDifferentiableFunction. It extends MultivariateFunction,
but since 3.1 it uses DerivativeStructure wich is good for symbolic calculations but is not
convinient for empirical and user defined functions. Perhaps it would be usefull to introduce
some additional interfaces for vector to double and vector to vector differentiable functions?
