**What's new in NMath V4.0?**

· **Fast Fourier Transforms (FFTs)-** NMath 4.0 contains high performance, multi-core aware FFT classes. This set of classes will support all common 1D and 2D FFT computations in a robust easy-to-use object-oriented interface. All classes will efficiently support FFT’s of arbitrary length, with a simple interface for both in-place and out-of-place computations. Additionally, there is a parallel set of classes for single precision computation.

· **Levenberg****-Marquardt Nonlinear Least Squares** - NMath 4.0 includes class LevenbergMarquardtMinimizer for minimizing the L2 norm of a function using the Levenberg-Marquardt algorithm (LMA). LMA is a standard in non-linear optimization, and is widely used for solving generic curve-fitting problems. LMA significantly outperforms gradient descent and conjugate gradient methods for medium sized problems, and complements the Trust Region minimizer already in NMath.

· **Linear Spline Interpolation-** NMath 4.0 includes a class LinearSpline for representing a function whose values are determined by linear interpolation between tabulated values.

· **MKL Version 10.2 -** NMath 4.0 now leverages Intel’s MKL Version 10.2. This provides many performance improvements for faster execution and taking advantage of more cores. It now also can take advantage of threading on more cores and more CPUs. These speed improvements generally range from 10% to 25%, and if you have a 24 core machine, the improvement can be as high as 130 times as great.

· **AnyCPU**** configuration** - Use AnyCPU configuration to build one application that automatically loads native x86 or x64 code as required.

__NMath____ Core__

NMath Core is part of CenterSpace Software’s NMath product suite, which provides object-oriented components for math, engineering, scientific, and financial applications on the .NET platform. NMath Core is the foundational library in the suite, and provides basic numerical building blocks such as vector and matrix classes, complex number classes, and random number generators. For most computations, NMath Core uses machine-specific, highly-optimized versions of the C and FORTRAN public domain computing packages known as the BLAS (Basic Linear Algebra Subroutines) and LAPACK (Linear Algebra PACKage). This gives NMath Core classes performance levels comparable to C, and often results in performance an order of magnitude faster than non-platformoptimized implementations.

Fully compliant with the Microsoft Common Language Specification, all NMath Core routines are callable from any .NET language, including C#, Visual Basic.NET, and Managed C++.

**NMath**** Core Product features include:**

· Single- and double-precision complex number classes

· Full-featured vector and matrix classes for single- and double-precision floating point numbers and single- and double-precision complex numbers

· Flexible indexing using slices and ranges

· Cubic spline interpolation

· Extension of standard mathematical functions, such as Cos(), Sqrt(), and Exp(), to work with vectors, matrices, and complex number classes

· LU factorization for a matrix, as well as functions for solving linear systems, computing determinants, inverses, and condition numbers

· Least squares solutions

· Random number generation from various probability distributions, including the uniform, normal, Poisson, gamma, binomial, exponential, Pareto, and log normal distributions

· Classes for encapsulating functions of one variable, with support for numerical integration (Romberg and Gauss-Kronrod methods), differentiation (Ridders' method), and algebraic manipulation of functions

· Polynomial encapsulation, interpolation, and exact differentiation and integration.

· Source code version available

· Prebuilt 64-bit assemblies are included

__NMath____ Analysis__

NMath Analysis contains classes for function minimization, root-finding, and linear programming.

**NMath**** Analysis Product features include:**

· 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.

· Linear programming using the simplex method.

· Least squares polynomial 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.

__NMath____ Matrix__

NMath Matrix is part of CenterSpace Software’s NMath product suite, which provides object-oriented components for mathematical, engineering, scientific, and financial applications on the .NET platform. NMath Matrix extends the foundational library NMath Core to include structured sparse matrix classes and factorizations, general matrix decompositions, advanced least squares solutions, and solutions to eigenvalue problems.

Like NMath Core, NMath Matrix uses machine-specific, highly-optimized versions of the BLAS and LAPACK for most computations. This gives NMath Matrix classes performance levels comparable to C or Fortran. NMath Matrix is an advanced matrix manipulation library that extends NMath Core to include structured sparse matrix classes (triangular, symmetric, Hermitian, banded, tridiagonal, symmetric banded, and Hermitian banded), factorizations (LU, Bunch-Kaufman, and Cholesky), orthogonal decompositions (QR and SVD), advanced least squares classes (Cholesky, QR, and SVD), and solutions to symmetric, Hermitian, and nonsymmetric eigenvalue problems.

Fully compliant with the Microsoft Common Language Specification, all NMath routines are callable from any .NET language, including C# and Visual Basic.NET. For most computations, NMath libraries use proven, highly optimized versions of public domain linear algebra subroutine libraries, such as the BLAS and LAPACK. This gives NMath routines accuracy you can trust, and performance levels comparable to C or Fortran, combined with state of the art, object-oriented interfaces that leverage the full power of the .NET platform.
