**Chapter
24. **** ****The Analysis Namespace** (.NET, C#, CSharp, VB, Visual Basic, F#)

The CenterSpace.NMath.Core namespace provides the following analytical classes:

● 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) using the Microsoft Solver Foundation.

● 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, fzero 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
