Chapter 22. The Analysis Namespace (.NET, C#, CSharp, Visual Basic, VB.NET)

The CenterSpace.NMath.Analysis namespace provides:

• Classes for minimizing univariate functions using golden section search and Brent's method.
• Classes for minimizing multivariate functions using the downhill simplex method, Powell's direction set method, the conjugate gradient method, and the variable metric (or quasi-Newton) method.
• Simulated annealing.
• Classes for linear programming (LP), non-linear programming (NLP), and quadratic programming (QP).
• Least squares polynomial fitting.
• Nonlinear least squares minimization, curve fitting, and surface fitting.
• Classes for finding roots of univariate functions using the secant method, Ridders' method, and the Newton-Raphson method.
• Numerical methods for double integration of functions of two variables.
• Nonlinear least squares minimization using the Trust-Region method, a variant of the Levenberg-Marquardt method.
• Curve and surface fitting by nonlinear least squares.
• Solutions to first order initial value differential equations by the Runge-Kutta method

To avoid using fully qualified names, preface your code with an appropriate namespace statement. For example, in C#:

using CenterSpace.NMath.Analysis;

In Visual Basic.NET:

Imports CenterSpace.NMath.Analysis

NOTE- In most cases, you must also preface your code with a namespace statement for the CenterSpace.NMath.Core namespace (Chapter 2).
