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. If you are interested in evaluating NMath Matrix, we offer a free fully-functional trial version, distributed in binary form only for a 30-day evaluation period.NMath Core 2.3Trevor Misfeldthttp://downloads.embarcadero.com/Item/203192007-08-08T21:02:08-07:002007-08-08T21:02:08-07:00Vector, matrix, complex numbers, random numbers, integration, cubic splines and high-performance functions for object-oriented .NET numerics. Interfaces to the BLAS and LAPACK.NMath Core contains foundational classes for object-oriented numerics on the .NET platform. 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. If you are interested in evaluating NMath Core, we offer a free fully-functional trial version, distributed in binary form only for a 30-day evaluation period.
