Konstantin Berlin created MATH-1069:
---------------------------------------
Summary: Make RealLinearOperator an interface
Key: MATH-1069
URL: https://issues.apache.org/jira/browse/MATH-1069
Project: Commons Math
Issue Type: Improvement
Affects Versions: 4.0, 3.3
Reporter: Konstantin Berlin
Priority: Minor
The conjugate gradient package requires only a very limited set of methods to
function. In many instances it might not be as convenient to extend an abstract
class, rather than just to add an interface to already existing classes.
>From a style point of view, there is no code that all possible implementations
>of RealLinearOperator would share or even benefit from, so there is no need
>for an abstract class.
