NMath

NMath is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand NMath rather than just read about it. In short: NMath is a numerical package for the Microsoft .NET Framework. It is developed by CenterSpace Software.

Key takeaways

NMath belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect NMath to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NMath from memory before moving on to harder problems.

Reference excerpt

NMath is a numerical package for the Microsoft .NET Framework. It is developed by CenterSpace Software. Version 1.0 was released in March, 2003 as NMath Core. The current version is called NMath 7.1, released in December, 2019. NMath is built on MKL, a numerical library from Intel. As of 2023, NMath sells at US$1,595.

Features NMath contains vector and matrix classes, complex numbers, factorizations, decompositions, linear programming, minimization, root-finding, structured and sparse matrix, least squares, polynomials, simulated annealing, curve fitting, numerical integration and differentiationing.

CenterSpace Software

CenterSpace Software, LLC. is a commercial software development company with headquarters in Corvallis, Oregon, USA, that produces numerical and statistical class libraries for the .NET Framework and the NMath software. CenterSpace also provides advanced software project consulting services. CenterSpace Software produced the first commercial .NET numerical class library in March, 2003. Developers at CenterSpace Software wrote the book The Elements of C# Style. CenterSpace won the Willamette Angel Conference in 2009.

Worked examples

Example 1 — a first encounter with NMath

Start with the simplest possible case. Write down what NMath claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to NMath before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about NMath ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of NMath

In research: NMath appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses NMath in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: NMath is common in secondary-school and first-year university syllabi. It links to neighbouring topics .NET programming tools, C Sharp libraries, Component-based software engineering, so understanding it makes those chapters shorter.
In everyday life: Look for NMath outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is NMath in simple terms?

NMath is a numerical package for the Microsoft .NET Framework. It is developed by CenterSpace Software.

Why does NMath matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study NMath?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.

What does this page cover?

It gives you a compact reference excerpt plus original lgStudy explanations, examples, applications and study material on NMath.
