Struct SlogdetResult

pub struct SlogdetResult<T, R = T>where
    T: Scalar,
    R: Scalar,{
    pub sign: Tensor<T>,
    pub logabsdet: Tensor<R>,
}

Expand description

Sign-and-log-determinant result: det(A) = sign * exp(logabsdet).

§Examples

use tenferro_device::LogicalMemorySpace;
use tenferro_linalg::slogdet;
use tenferro_prims::CpuContext;
use tenferro_tensor::{MemoryOrder, Tensor};

let mut ctx = CpuContext::new(1);
let a = Tensor::<f64>::zeros(
    &[3, 3],
    LogicalMemorySpace::MainMemory,
    MemoryOrder::ColumnMajor,
).unwrap();
let result = slogdet(&mut ctx, &a).unwrap();
assert_eq!(result.sign.ndim(), 0);

Fields§

§sign: Tensor<T>

Sign of the determinant.
