Function: Natural and Contrained Cubic Spline
Function

Function to calculate the natural cubic spline of a data set. This draws a smooth curve through a series of data points. There is also a constrainedcubicspline() function which has clamped ends. This avoids the oscillations that can sometimes appear at the end of spline fitted curves or where data bunches. However, the constrainedcubicspline() function does this at the expense of smoothness.
