Spline Toolbox CD

The Spline Toolbox extends MATLAB® with tools for creating, viewing, and analyzing spline approximations of data. Splines are smooth piecewise polynomials that can be used to represent functions over large intervals, where it would be impractical to use a single approximating polynomial. They have become a standard tool for modeling arbitrary functions.

The Spline Toolbox includes a graphical user interface (GUI) that provides easy access to functions for creating, visualizing, and manip- ulating splines. The toolbox also contains functions that enable you to evaluate, plot, combine, differentiate, and integrate splines.

Because all toolbox functions are imple-mented in the open MATLAB language, you can inspect the algorithms, modify the source code, and create your own custom functions.

• GUIs that let you create, view, and manipulate splines and manage and compare spline approximations
• Functions for advanced spline operations, including differenti- ation, integration, break/knot manipulation, and optimal knot placement
• Support for piecewise polynomial form (ppform) and basis form (B-form) splines
• Support for tensor-product splines and rational splines (including NURBS)
