------------------------------------
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?
