Cortex Compute Engine

Symbolic manipulation and numeric evaluation of MathJSON expressions

MathJSON is a lightweight mathematical notation interchange format based on JSON.

The Cortex Compute Engine can parse LaTeX to MathJSON, serialize MathJSON to LaTeX, format, simplify and evaluate MathJSON expressions.

Reference documentation and guides at cortexjs.io/compute-engine.

Using Compute Engine

$ npm install --save @cortex-js/compute-engine

import { parse, evaluate } from '@cortex-js/compute-engine';

const expr = parse('2^{11}-1 \\in \\P');

console.log(expr);
// ➔ ["Element", ["Subtract", ["Power", 2, 11] , 1], "PrimeNumber"]

console.log(evaluate(expr));
// ➔ "False"

Changelog

0.18.1 2023-10-16

Issues Resolved

• Parsing of whole numbers while in rational mode would return incorrect results.
• The ND function to evaluate derivatives numerically now return correct values.

ce.parse("\\mathrm{ND}(x \\mapsto 3x^2+5x+7, 2)").N();
// -> 17.000000000001

Improvements

• Speed up NIntegrate by temporarily switching the numeric mode to machine while computing the Monte Carlo approximation.
