Abstract :
The problem of data interpolation is one with which most engineers are quite familiar. Many results, obtained from experiments, are presented in the form of graphs, in which a number of measured points have been plotted and a curve has then been drawn through these points to represent the behaviour of the variable between the measured points. In general, such interpolation of data is done by a human being who, either free-hand, or with the help of French curves tries to produce a “smooth” curve which encompasses all the measured points.
