Arya

A mini numerical-computation library

This library is an extended offshoot of a physics engine that's currently under development and is still at its nascent phase, so expect frequent updates!

You can perform matrix calculations

``typescript
import { Matrix2D } from "arya-math";

const a = new Matrix2D([
[1, 2, 3],
[4, 5, 6],
[7, 8, 0],
]);

const determinant = a.det(); // 27

const chainedVal = a.inverse()?.scalarAdd(3).transpose().det(); // 4.037
`

solve a system of linear equations

`typescript
import { Cramer } from "arya-math";

const system = new Cramer([
[7, 1, -5, -1], // 7x + y - 5 = -1
[4, 3, 1, 0], // 5x + 3y + 1 = 0
[6, 9, -2, 8], // 6x + 9y - 2 = 8
]);

const solution = system.solve();
// x: -0.79,
// y: 1.27,
// z: -0.65,
`

evaluate algebraic expressions

`typescript
import { evaluateExp } from "arya-math";

const result = evaluateExp(
{
x: 2,
y: 3,
},
"2x + y(2x^y + yx) + 8y(y+2)"
);

console.log(result); // 190
`

or play around with Vectors!

`typescript
import { Vector3 } from "arya-math";

const vec = new Vector3(2, 3, 4);

const transformation = vec.scale(3).cross(new Vector3(3, 5, 0)).length(); // 70.035
