Subject [jira] [Updated] (MATH-1202) PiecewiseBicubicSplineInterpolatingFunction - allow to extrapolate
Date Fri, 13 Feb 2015 11:38:13 GMT

     [ https://issues.apache.org/jira/browse/MATH-1202?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

dmitry dementiev updated MATH-1202:
-----------------------------------
    Description: 
PiecewiseBicubicSplineInterpolatingFunction is not able to interpolate if the value we want
to calculate is out of the points/values. Other libs provide functionality to make some extrapolation.

In geospatial analysis, for example it is a must have feature, because the locations of points
and values are almost always not at the border of the shape that we want to interpolate.
