Abstract
In many disciplines there is a need for efficient interpolation of irregular spaced data. For unsampled locations values have to be computed from the available data. Usually we are interested in smooth interpolations, and artificial oscillations 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.
