Linear Algebra API

In addition to exporting convenience classes representing a variety of linear algebra-related data types, each such type also has its own module that exports individual functions. For example, a two-by-two matrix can be imported in two different ways:

import { Matrix2 } from "@lakuna/umath";

import Matrix2 from "@lakuna/umath/Matrix2";

Using the convenience class, multiplying two two-by-two matrices would look like this:

import { Matrix2 } from "@lakuna/umath";

const a = Matrix2.fromValues(0, 1, 2, 3);
const b = Matrix2.fromValues(4, 5, 6, 7);
const c = a.multiply(b);

Using the raw functions, it could instead look like this:

import { multiply } from "@lakuna/umath/Matrix2";

const a = [0, 1, 2, 3];
const b = [4, 5, 6, 7];
const c = multiply(a, b, [0, 0, 0, 0]);
