Network Based Optimization Project is a network transparent system for global optimization problems using client-server model.

The solid and structural mechanics module for Netgen/NGSolve. It allows to solve linear and non-linear static and dynamic problems.

NGSolve is a general purpose Finite Element Library on top of Netgen. With the basic library one can solve heat flow equations, Maxwell equations, and solid mechanical problems. Several add-ons are available for particular application classes. New paper: J. Schöberl: "C++11 Implementation of Finite Elements in NGSolve", ASC Report 30/2014, Institute for Analysis and Scientific Computing, Vienna University of Technology, 2014 http://www.asc.tuwien.ac.at/~schoeberl/wiki/publications/ngs-cpp11.pdf

The NHD Software Project is a collection of the utilities, scripts, APIs, standards, and application extensions used for the quality assurance of stream and river data, conflation/generalisation of hydrographic data, and other hydrologic data maintenance.

Nonlinear Krylov Acceleration (NKA) is a method for accelerating the convergence of fixed-point (Picard) iterations. Many Newton-like and inexact Newton methods are fixed point iterations. The NKA project provides the canonical implementation of the method for several programming languages. The black-box accelerator is simple to integrate into existing code. Placed in the iteration loop, it observes the sequence of solution updates and replaces them with improved updates using information it has gleaned from previous solution iterates. It was only recently recognized (2011) that NLK is essentially equivalent to Anderson Acceleration for a specific choice of mixing parameter. NLK was independently devised in the late 1980's using a very different approach, and though it leads to the same algebraic method, NLK's organization is somewhat different, and arguably superior. The NLK approach also provides clear rationale for the proper choice of Anderson's arbitrary mixing parameter.

NLISP is an extension to Common Lisp that provides an interactive numerical computation environment, similar to packages like Matlab and IDL. NLISP has array syntax, scientific plotting and a numerical library. It currently runs under CMUCL & SBCL Lisp.

A Python environment for large and sparse linear and nonlinear optimization using intuitive interfaces to linear algebra tools and subproblem solvers written in low-level languages. It provides building blocks to experiment with new ideas and algorithms.

Mit NMaze kann man Zahlenrätsel erstellen und lösen lassen. Man beginnt mit einem Quadrat und formt dann Abhängigkeiten in Form von Operationen und Zugehörigkeiten bezüglich Mengen.

NOMAD is a C++ code that implements the MADS algorithm (Mesh Adaptive Direct Search) for difficult blackbox optimization problems. Such problems occur when the functions to optimize are costly computer simulations with no derivatives.

Nprim calculate the primes numbers. This software was written and compiled in FreePascal Compiler. Works in DOS and LINUX OS.

NSB entropy and mutual information estimator; applications to the analysis of neural code.

The NSketch library provides implementations of most common sketch-based algorithms (histograms, quantile, frequent items, bloom filter ...). The library is written in C# for .Net.

NT2 is a multi-platform C++ library providing various template matrix classes that can be used with a Matlab(tm) like syntax whose performances are close to those obtained with hand written C code. NT2 comes with various numerical toolboxes.

A C++ matrix class for creating matrix objects and easily performing elementary operations between matrix objects including addition, subtraction, multiplication, transposition, and trace.

The NUMIPAD library implements several methods/algorithms to solve inverse problems and adaptive decomposition (i.e. Tikhonov regularization, Total Variation, Basis Pursuit, etc.)

Nan.System.Platform v.1.1 (Beta) Platform-level utilities on .NET Framework 4.0 (C#) NOTE: Requires the MS Visual C++ Run-Time (msvcrt.dll).

Napkin (also titled “An Infinitely Large Napkin”) is a lightweight, semi-formal introduction to higher mathematics, aimed at giving readers a bird’s-eye view over various mathematical fields. It is not a polished textbook full of full proofs; rather it offers clean definitions, theorem statements, intuitive motivations, and informal sketches of why things work, with the goal of building conceptual understanding. The coverage spans undergraduate and early graduate topics, designed to show how different areas of math fit together—linear algebra, analysis, topology, number theory, and more—without going deeply into every subtopic. Because it is written in LaTeX (with supporting Asymptote or other tools), readers can compile their own version, and the repository integrates diagrams, flowcharts, and supplementary files.
