Struct LuFactorResult

Source

pub struct LuFactorResult<T: Scalar> {
    pub factors: Tensor<T>,
    pub pivots: Tensor<i32>,
}

Expand description

Packed LU factorization result.

§Examples

use tenferro_linalg::lu_factor;
use tenferro_prims::CpuContext;
use tenferro_tensor::{MemoryOrder, Tensor};

let mut ctx = CpuContext::new(1);
let a = Tensor::from_slice(&[2.0_f64, 1.0, 1.0, 3.0], &[2, 2], MemoryOrder::ColumnMajor)
    .unwrap();
let result = lu_factor(&mut ctx, &a).unwrap();
assert_eq!(result.pivots.len(), 2);

Fields§

§factors: Tensor<T>

Packed LU factors with the same shape as the input.

§pivots: Tensor<i32>

Backend pivot tensor in 1-indexed step-pivot form.
