Enum CompressionMethod 

pub enum CompressionMethod {
    LU,
    CI,
    SVD,
}

Matrix decomposition method used during TT compression.

The method controls how each bond is factored during the right-to-left truncation sweep.

Examples

use tensor4all_simplett::CompressionMethod;

let method = CompressionMethod::default();
assert_eq!(method, CompressionMethod::LU);

Variants

LU

Rank-revealing LU decomposition (default).

Fast and robust for most use cases.

CI

Cross-interpolation (CI) decomposition.

Can be faster than LU for very large bond dimensions because it avoids dense matrix operations.

SVD

Singular value decomposition (SVD).

Gives the optimal low-rank approximation (Eckart–Young theorem) but is more expensive than LU or CI.

Trait Implementations

impl Clone for CompressionMethod

fn clone(&self) -> CompressionMethod

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CompressionMethod

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for CompressionMethod

fn default() -> CompressionMethod

Returns the “default value” for a type.

impl PartialEq for CompressionMethod

fn eq(&self, other: &CompressionMethod) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for CompressionMethod

impl Eq for CompressionMethod
