Nelson 1.15.0.0

The main homepage for Nelson can be found at https://nelson-lang.github.io/nelson-website/.

Introduction

Nelson is a powerful, open-source 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 GNU 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.
