平滑z分数峰值检测器

描述

Rust对平滑z分数算法的实现。

用法

将以下内容添加到您的 Cargo.toml

[dependencies]
smoothed_z_score = "0.1"

并将其添加到您的crate根目录

extern crate smoothed_z_score;

示例用法

考虑以下数据集（来自原始stackoverflow回复）

    use smoothed_z_score::{Peak, PeaksDetector, PeaksFilter};

    fn main() {
        let input = vec![
            1.0, 1.0, 1.1, 1.0, 0.9, 1.0, 1.0, 1.1, 1.0, 0.9, 1.0, 1.1, 1.0, 1.0, 0.9, 1.0, 1.0, 1.1, 1.0,
            1.0, 1.0, 1.0, 1.1, 0.9, 1.0, 1.1, 1.0, 1.0, 0.9, 1.0, 1.1, 1.0, 1.0, 1.1, 1.0, 0.8, 0.9, 1.0,
            1.2, 0.9, 1.0, 1.0, 1.1, 1.2, 1.0, 1.5, 1.0, 3.0, 2.0, 5.0, 3.0, 2.0, 1.0, 1.0, 1.0, 0.9, 1.0,

        ];
        let output: Vec<_> = input
            .into_iter()
            .enumerate()
            .peaks(PeaksDetector::new(30, 5.0, 0.0), |e| e.1)
            .map(|((i, _), p)| (i, p))
            .collect();
        assert_eq!(output, vec![
            (45, Peak::High), (47, Peak::High), (48, Peak::High), (49, Peak::High),
            (50, Peak::High), (51, Peak::High), (58, Peak::High), (59, Peak::High),
            (60, Peak::High), (61, Peak::High), (62, Peak::High), (63, Peak::High),
            (67, Peak::High), (68, Peak::High), (69, Peak::High), (70, Peak::High),
        ]);
    }
