Data Interpolations

In numerical analysis, interpolation is a method of constructing new data points within the range of a discrete set of known data points. In science and engineering, we often will have a number of data points obtained by sampling and experimentation, and we must try to construct a function that closely fits those data points. This process is usually called curve fitting or regression analysis. Interpolation can be regarded as a special case of curve fitting in which the function must pass exactly through the data points. This implicitly assumes that the given data points in an interpolation are accurate and distinct. ...
