Ngmath example 7
Illustrates the use of ftcurv, ftcurvd, and ftcurvi.
This example can be created using NCL. It demonstrates how to use the Fitgrid package to fit an interpolatory spline under tension to a sequence of functional values (Fitgrid is part of the Ngmath library). Derivatives of the interpolated spline are also calculated, as well as integrals. The name of the source file for this example is nm07n.ncl.
Discussion
This module discusses how to use the Fitgrid package from within NCL.
