Subject [jira] [Created] (MATH-1069) Make RealLinearOperator an interface
Date Mon, 02 Dec 2013 14:39:35 GMT
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.
