[->] 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.
