javascript-cas
Javascript CAS is a simple computer algebra system designed for client-side use in web apps (and node.js).
Including math.js in your web pages will create a single global object M(str, context), which is a function that parses a latex expression string.
var y = M('x^2 + 3');
// Differentiate with respect to x
var dy = y.differentiate(y.unbound.x);
// Compile a javascript function
var fn = dy.compile('x');
// now evaluation of the deriviative is fast:
var x = fn(3.1); // Returns a javascript number.
Features
- Parsing latex expressions efficiently
- Differentiation Export string representations of functions:
- javascript:
.s('text/javascript'); - GLSL shaders:
.s('x-shader/x-fragment'); - Latex:
.s('text/latex'); - Complex Numbers
- Sums
- Vectors (dot products, cross products, gradient/curl etc).
- Finding roots (intersections) (Not yet implemented)
- Finding singularities (Not yet implemented)
