Function batch_stddev_f64 

pub fn batch_stddev_f64(values: &[f64]) -> f64

SIMD-friendly standard deviation.

Returns square root of population variance.

Example

use presentar_core::simd::batch_stddev_f64;
let values = vec![2.0, 4.0, 4.0, 4.0, 5.0, 5.0, 7.0, 9.0];
let stddev = batch_stddev_f64(&values);
assert!((stddev - 2.0).abs() < 0.001);
