Function sub_simd 

pub fn sub_simd<F>(a: &ArrayView1<'_, F>, b: &ArrayView1<'_, F>) -> Array1<F>
where
    F: Float + SimdUnifiedOps,

SIMD-accelerated element-wise subtraction

Computes a - b element-wise.

Arguments

• a - First array
• b - Second array

Returns

Element-wise difference

Examples

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

let a = array![5.0_f64, 7.0, 9.0];
let b = array![1.0_f64, 2.0, 3.0];
let c = sub_simd::<f64>(&a.view(), &b.view());
assert!((c[0] - 4.0).abs() < 1e-14);
assert!((c[1] - 5.0).abs() < 1e-14);
assert!((c[2] - 6.0).abs() < 1e-14);

Use Cases

• Gradient computation
