Subject [jira] Commented: (MATH-365) Issue with "SmoothingBicubicSplineInterpolator"
Date Tue, 20 Apr 2010 18:56:50 GMT


Luc Maisonobe commented on MATH-365:

removing the test class would badly impact test coverage, so it would be better to simply
deprecae it also and to remove the library class and its associated test class together when
releasing 3.0

> Issue with "SmoothingBicubicSplineInterpolator"
> -----------------------------------------------
>                 Key: MATH-365
>                 URL:
>             Project: Commons Math
>          Issue Type: Bug
>    Affects Versions: 2.1
>            Reporter: Gilles
>            Priority: Minor
> I figured out that the name of this class is misleading as the implementation doesn't
perform the intended smoothing.
> In order to solve this issue, I propose to:
> # deprecate the "SmoothingBicubicSplineInterpolator" class
> # create a "BicubicSplineInterpolator" class (similar to the above class but with the
useless code removed)
> # remove the "SmoothingBicubicSplineInterpolatorTest" class
> # add a "BicubicSplineInterpolatorTest" with essentially the same contents as the above
> Then I would also add a new "SmoothingPolynomialBicubicSplineInterpolator" where I used
the "PolynomialFitter" class to smooth the input data along both dimensions before the interpolating
function is computed.
> Does someone object to these changes?
