Subject [jira] [Created] (MATH-1243) Refactor "microsphere interpolation" implementation
Date Sat, 27 Jun 2015 10:39:04 GMT
Gilles created MATH-1243:
----------------------------

             Summary: Refactor "microsphere interpolation" implementation
                 Key: MATH-1243
                 URL: https://issues.apache.org/jira/browse/MATH-1243
             Project: Commons Math
          Issue Type: Improvement
            Reporter: Gilles
            Assignee: Gilles
            Priority: Minor
             Fix For: 4.0, 3.6


The microsphere interpolation implemented in {{o.a.c.m.analysis.interpolation.MicrosphereInterpolator}}
and its supporting class
{{o.a.c.m.analysis.interpolation.MicrosphereInterpolatingFunction}}
is not flexible enough for some uses.
For example it does not allow to share a microsphere between interpolating function instances
(and it always generates it from randomly generated normals).
Also the extrapolation feature cannot be controlled, leading to sometimes unwanted artefacts.
