symbolic-math

symbolic-math is a Javascript (Typescript) library for symbolic mathematics.

Example

import { createScriptEngine } from "symbolic-math";

const lines: string[] = [
    `a/b`
];

const eng = createScriptEngine();

const { values } = eng.executeScript(lines.join('\n'));
assert.strictEqual(eng.renderAsInfix(values[0]), "a/b");
assert.strictEqual(eng.renderAsSExpr(values[0]), "(* a (power b -1))");
assert.strictEqual(eng.renderAsLaTeX(values[0]), "\\frac{a}{b}");

eng.release();

symbolic-math is a fork of Algebrite by Davide Della Casa. The fork adds Geometric Algebra, S.I. Units of Measure, and changes the way that expressions are matched and transformed.

Algebrite started as a port of the EigenMath CAS by George Weigt to TypeScript. Another fork of EigenMath: SMIB by Philippe Billet.

Another CAS of similar nature is SymPy made in Python.

Three other Javascript CAS are

• javascript-cas by Anthony Foster supporting "differentiation, complex numbers, sums, vectors (dot products, cross products, gradient/curl etc)"
• Coffeequate by Matthew Alger supporting "quadratic and linear equations, simplification of most algebraic expressions, uncertainties propagation, substitutions, variables, constants, and symbolic constants".
• Algebra.js by Nicole White which among other things can build and solve equations via a "chainable" API.
