Source 
pub fn mean_simd<F>(a: &ArrayView1<'_, F>) -> F
where
    F: Float + SimdUnifiedOps,
Expand description

SIMD-accelerated array mean

Computes the arithmetic mean: mean = sum(x) / n

§Arguments

  • a - Input array

§Returns

Arithmetic mean of elements

§Examples

use scirs2_core::ndarray::array;
use scirs2_core::ndarray_ext::elementwise::mean_simd;

let x = array![1.0_f64, 2.0, 3.0, 4.0, 5.0];
let m = mean_simd::<f64>(&x.view());
assert!((m - 3.0).abs() < 1e-14);

§Use Cases

  • Central tendency measurement
  • Batch normalization (compute running mean)
  • Signal averaging
  • Expected value estimation
