Nelson is a powerful numerical computational language, developed to provide a comprehensive and intuitive environment for engineers, scientists, and students. With over 1,200 built-in functions, Nelson supports a wide range of tasks, from basic algebra to advanced numerical simulations.
Originally inspired by languages like MATLAB© and Octave, Nelson offers users a lightweight yet feature-rich experience. It is designed to be easy to learn and use, with an emphasis on performance and flexibility.
It has sophisticated data structures (including cell, struct, 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.
This is free and open source software.
