Package Exports

ginac-wasm

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (ginac-wasm) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

WebAssembly bindings for the GiNaC computer algebra system

Usage

const { initGiNaC, getFactory } = require('ginac-wasm');

(async () => {
  const GiNaC = await initGiNaC('ginac-wasm/dist/ginac.wasm');
  const g = getFactory();

  console.log(
    GiNaC([
      // 2 * 3 = 6
      g.mul(g.numeric('2'), g.numeric('3')),
      // x + 2x = 3x
      g.add(g.symbol('x'), g.mul(g.numeric('2'), g.symbol('x'))),
      // (2*sin(x))' = 2*cos(x)
      g.diff(g.mul(g.numeric('2'), g.sin(g.symbol('x'))), g.symbol('x')),
      // internal parser of GiNaC
      g.parse('x^3 + 3*x + 1') 
    ]),
  );

  console.log(
    GiNaC([
      g.numeric('2'),
      g.numeric('3'),
      // reference first and second items from the array => 2*3 = 6
      g.mul(g.ref(0), g.ref(1))
    ]),
  );

  // besides the string output format,
  // it can also generate traversable json structures
  console.dir(
    GiNaC([
      // 2*sin(x)
      g.mul(g.numeric('2'), g.sin(g.symbol('x'))),
    ], { json: true }),
    { depth: null }
  );
})();
