Solve nonlinear systems of equations using Newton's method.

[->] Nexsys

An equation solving program written in Rust 🦀

Nexsys (iNtuitive Equations, eXpressions, and SYStems) is inspired by Engineering Equation Solver (EES), which is a program intended for engineers working with thermal or fluids-heavy systems. This tool allows engineers to develop massive mathematical models of the systems they work with and produce optimized designs in less time than it might take to develop the same model in Python or Matlab.

The main drawback of EES is its closed-source nature and poor ability to integrate with non-Windows machines and other software, so with an interest in simulation and computer-aided engineering, I took it upon myself to fill the gap.

The nexsys-core Crate

This is the nexsys-core sub-crate, which is responsible for providing from-scratch implementations of Newton's method for solving both single-unknown equations and nonlinear systems of equations, as well as the Nexsys solver engine.

The main point of access for the Nexsys solver is the Nexsys struct, which interprets raw text as a sort of pseudo-code in order to determine what equations can and can't be solved and in what order.
