Function qr_factor 

pub fn qr_factor<F>(a: &ArrayView2<'_, F>) -> LinalgResult<QRDecomposition<F>>
where
    F: Float + NumAssign + Sum + Send + Sync + ScalarOperand + 'static,

Performs QR decomposition using Householder reflections.

Arguments

• a - Input matrix

Returns

• QR decomposition result

Examples

use scirs2_core::ndarray::{array, ScalarOperand};
use scirs2_linalg::lapack::qr_factor;

let a = array![[2.0, 1.0], [4.0, 3.0], [8.0, 7.0]];
let qr_result = qr_factor(&a.view()).unwrap();

// Check that A = Q*R
// (implementation dependent, so not shown here)
