Trait LapackEigScalar 

pub trait LapackEigScalar: LinalgScalar {
    // Required methods
    fn eig_buffer_sizes(n: usize) -> (usize, usize);
    fn eig_ri_to_complex(
        n: usize,
        val_ri: &[Self],
        vec_ri: &[Self],
        values_out: &mut [Self::Complex],
        vectors_out: &mut [Self::Complex],
    );
}

LAPACK-oriented eigen helper contract for CPU eigendecomposition paths.

This trait is intentionally narrower than LinalgScalar. It exists so CPU eigensolver glue can request the real/imag buffer conversion helpers it needs without forcing every backend-generic scalar contract to carry LAPACK details.

Examples

use tenferro_linalg_prims::LapackEigScalar;

let (vals, vecs) = <f64 as LapackEigScalar>::eig_buffer_sizes(2);
assert_eq!((vals, vecs), (4, 8));

Required Methods

fn eig_buffer_sizes(n: usize) -> (usize, usize)

Return the temporary value/vector buffer sizes used by the CPU eig path.

fn eig_ri_to_complex( n: usize, val_ri: &[Self], vec_ri: &[Self], values_out: &mut [Self::Complex], vectors_out: &mut [Self::Complex], )

Convert LAPACK-style real/imag outputs into complex values/vectors.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
