# A cubic spline interpolation of unequally spaced data points

## Description

Title of program: CUSPLN Catalogue Id: ACYV_v1_0 Nature of problem Quite often an experiment results in a series of discrete data points inthe interval (x0,xN). The theorist then wishes to interpolate this data at some point x epsilon(x0,xN) or at a large number of points covering the domain (x0,xN) so that an interpolating curve may be drawn. The theorist may also wish to interpolate the discrete data points in order to i)calculate the length of the curve through the data points ii)calculate the area under the curve through the data points or iii)calculate the ...
