sac-tool

The math tool written in Rust

一款基于 Rust 实现的 数据计算

Install

$ npm i @nevule/sac-tool

Usage

import * as sac from '@nevule/sac-tool';
// 获取离群元素
sac.outliers(new Float64Array([1, 2, 3, 4, 3, 1, 2, 4, 10, 15])); // => [10, 15]

// Promise版本
import { Calculate } from '@nevule/sac-tool';
const sac = new Calculate();
await sac.outliers(new Float64Array([1, 2, 3, 4, 3, 1, 2, 4, 10, 15])); // => Promise<[10, 15]>

Test

const numbers = (new Array(10000000).fill(1).map(() => Math.random() * 1000000));

console.time('js')
js.coefficientOfVariation(numbers)
console.timeEnd('js') // 1.119s

console.time('rust')
sac.coefficientOfVariation(new Float64Array(numbers))
console.timeEnd('rust') // 122.788ms

console.time('rust-wasm')
wasm.coefficientOfVariation(new Float64Array(numbers))
console.timeEnd('rust-wasm') // 164.442ms
