Module validate 

Singular-matrix validation helpers shared across backends and exec layers.

Examples

use tenferro_tensor::validate::validate_nonsingular_u;
use tenferro_tensor::{Tensor, TypedTensor};

let t = Tensor::F64(TypedTensor::from_vec(vec![2, 2], vec![1.0, 0.0, 0.0, 1.0]));
assert!(validate_nonsingular_u(&t).is_ok());

Traits

DiagSingularity

Trait for detecting singular or non-finite diagonal entries.

Functions

check_singular_diagonal

Checks that every diagonal element of a (possibly batched) upper-triangular factor is non-singular and finite.

validate_nonsingular_u

Validates that the upper-triangular factor u of a matrix decomposition has no singular (zero) or non-finite diagonal entries.
