Nelson is an array programming language providing a powerful open computing environment for
engineering and scientific applications using modern C/C++ libraries (Boost, Eigen, …)
and others state of art numerical libraries.
It has sophisticated data structures (including cell, struct, dictionary, linear systems, …),
an interpreter and a high level programming language.
Nelson has been developed to be an open/modular system where an user can define
these own data types and operations on these data types by using overload.

- Embedded Nelson code editor.
- Help engine:
Generate help files using Nelson dedicated functions.
View your generated help files as html, markdown, pdf, gitbook or directly in Nelson help viewer.
- Tests engine:
Validate your algorithm using Nelson dedicated functions.
Export the test results under the xUnit reports format.
- Profiling and Code coverage tools for Nelson's language:
Nelson has a built-in profiler that is very useful to profile your code and find out what script or function is taking the most time.
- [Nelson cloud](https://www.npmjs.com/package/nelson-cloud):
Instant access to Nelson anywhere from an web browser.
