A Mathematical/Statistical Control/Component by WebCab Components

WebCab Functions for .NET

A Mathematical/Statistical Control/Component for .Net, ActiveX, ASP.Net, C/C++, Delphi, Java

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. Interpolation procedures include Newton polynomials, Lagrange's formula, Burlisch-Stoer algorithm, Cubic splines (natural and free), Bicubic interpolation. Equation solver procedures include Van Wijngaarden-Dekker-Brent algorithm, interval bisection method, secant and false position, Newton-Raphson method and Ridders' method.

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 has the following feature:


  • ADO Mediator - The ADO Mediator assists the .NET developer in writing
    DBMS enabled applications by transparently combining the financial and
    mathematical functionality of our .NET components with the ADO.NET Database
    Connectivity model.
  • ASP.NET Web Application Examples - We provide an ASP.NET Web Application
    example which enables you to quickly test the functionality within this .NET Service.
  • ASP.NET Examples with Synthetic ADO.NET - we use a ASP.NET service to perform component
    calculations on SQL database columns from a remote DBMS. We apply a
    component's function to certain rows from the database and list the output in
    HTML format. This is a powerful feature since it allows you to perform
    calculations in a DBMS manner without having to code the C#to SQL
    database transaction yourself as it is all done by the ASP within the .NET
    Framework managed server side environment.
