| Applications / WebCab Functions v2.0 (J2EE Edition) |
We offer refined numerical procedures to either construct a function of one or two variables from a set of points (i.e. interpolate), or solve an equation of one variable. The interpolation procedures provided include Newton polynomials, Lagrange's formula, Burlisch-Stoer algorithm, Cubic splines (natural and free), Bicubic interpolation and procedures for find the interpolation functions coefficients. In order to solve an equation we provide the Van Wijngaarden-Dekker-Brent algorithm, interval bisection method, secant and false position, Newton-Raphson method and Ridders' method.
Product Details
This suite includes the following features:
Interpolation Module
- Polynomial Interpolation and extrapolation
- Lagrange's formula - for interpolating a function known at N points with a
polynomial of degree N-1
- Burlisch-Stoer algorithm - interpolates functions using rational functions,
this method gives error estimates
- Cubic Splines - we give algorithms for natural and clamped cubic splines
- Sorting - efficient techniques are used for finding tabulated values
- Coefficients of an Interpolating Polynomial
- Matrix method - this method relies upon diagonalizing a matrix (or
solving a system of equations), and is of the order N squared
- Zero method - by evaluating the interpolating polynomial at particular
values we deduce the coefficients, this method is of the order N cubed
- Interpolation and extrapolation in two or more dimensions
- Grid - functions can be interpolated on an n-dimensional grid
- Bilinear interpolation - we consider a multidimensional interpolation
by breaking the problem into successive one dimensional interpolations
- Accuracy - the use of higher order polynomials to obtain increased
accuracy
- Smoothness - the use of higher order polynomials to enforce
smoothness on some of the derivatives
- Bicubic interpolation - finds an interpolating function with a specified
derivatives and cross derivatives which vary smoothly at the grid points
- Bicubic spline - a special case of Bicubic interpolation involving the use
of successive one-dimensional splines
Equation Solver Module
- Interval Bisection Method - A robust method that always finds a solution
or a singularity inside a bracketed interval.
- Secant Method - Generally this procedure converges and is much faster than the
interval bisection method.
- Brent's Algorithm - The method of choice to find a bracketed root
of a one dimensional equation when you cannot easily compute the function's derivative.
- Ridders' Method - Concise and almost as reliable as Brent's
Algorithm for finding a bracketed root of an equation.
- Method of Regula Falsi - This procedure uses a slight alteration on
the secant method to ensure convergence. The procedure is generally faster than the interval
bisection method and slightly slower than the secant method.
- Newton-Raphson Method - Given a first approximation to a root and the
differential of the function this procedure will always produce a solution. We implement this procedure
for polynomial functions of one variable.
- Fail-Safe Newton-Raphson Method - This method combines the Newton-Raphson method
and the Interval Bisection Method in order to produce very stable and fast convergence. Given a first
approximation to a root and the differential of the function this procedure will always produce a solution.
This product also contains the following features:
- GUI Bundle - we bundle a suite of graphical user interface
JavaBean components (with 1, 2, 4 or site-wide license) allowing the
developer to plug-in a wide range of GUI functionality (including
charts/graphs) into their client applications
- EAR Files - we provide individual customized EAR files for
the most widely used application servers including IBM WebSphere 4.0/5.0,
BEA WebLogic 6.1/7.0, Oracle 9iAS, Sun ONE AppServer 7, Ironflare Orion
1.5.2/1.6.0, Borland AppServer 5.0, Sybase EAServer 3.6 and JBoss 2.4.4/3.0.0
- Self-Deploy - the relevant servers EAR file will be self-deployed
onto supported local application servers during the installation of the
self-install package. The supported application servers include IBM WebSphere
4.0/5.0, BEA WebLogic 6.1/7.0, Oracle 9iAS, Borland AppServer 5.0, Ironflare
Orion 1.5.2/1.6.0 and JBoss 2.4.4/3.0.0
- UML Models - to assist system architects we provide UML
