Struct CholeskyExResult

pub struct CholeskyExResult<T>where
    T: Scalar,{
    pub l: Tensor<T>,
    pub info: Tensor<i32>,
}

Expand description

Structured Cholesky result with numerical status information.

info contains one entry per batch matrix. Zero means success.

§Examples

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

let mut ctx = CpuContext::new(1);
let a = Tensor::from_slice(&[4.0_f64, 2.0, 2.0, 3.0], &[2, 2], MemoryOrder::ColumnMajor)
    .unwrap();
let result = cholesky_ex(&mut ctx, &a).unwrap();
assert_eq!(result.info.len(), 1);

Fields§

§l: Tensor<T>

Lower-triangular Cholesky factor.

§info: Tensor<i32>

Per-batch numerical status tensor.
