Exploring new options for data interpolation with radial basis functions

Research output: Contribution to book or proceedingConference articlepeer-review

Abstract

In many disciplines there is a need for efficient in terpolation of ir regular spaced data. For unsampled locations values have to be computed from the available data. Usually we are interested in smooth interpolations, and artificial o scillations should be avoided. For large data sets fully populated matrices are undesirable. The use of compactly supported basis functions appears to be attractive. In this paper radial basis functions satisfying the 2D bi-harmonic equation are used. Accurate interpolation could be achieved in the numerical test examples.
