Curve Fitting and Interpolation
A set of data may emanate from various sources. In many engineering and scientific applications, the data originates from conducting experiments that involve measurement of physical quantities; for instance, measuring the displacement of a coiled spring when subjected to tensile or compressive force. In other cases, the data may be generated as a result of using numerical methods; for instance, numerical solution of differential equations (Chapters 7, 8, and 10).
An available set of data can be used for different purposes. In some cases, the data is represented by a function, which in turn can be used for numerical differentiation or integration (Chapter 6). Such function may be obtained through curve fitting, ...
