Enum ShiftStrategy 

pub enum ShiftStrategy {
    ExplicitShift,
    FrancisDoubleShift,
    Wilkinson,
}

Shift strategy for implicit QZ steps.

Controls how the shift polynomial is chosen at each QZ iteration.

Variants

ExplicitShift

Use explicitly computed eigenvalues of the trailing 2×2 block.

FrancisDoubleShift

Francis implicit double-shift (standard choice for real matrices).

Wilkinson

Wilkinson shift (single-shift variant, more aggressive deflation).

Trait Implementations

impl Clone for ShiftStrategy

fn clone(&self) -> ShiftStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShiftStrategy

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

Formats the value using the given formatter.

impl Default for ShiftStrategy

fn default() -> ShiftStrategy

Returns the “default value” for a type.

impl PartialEq for ShiftStrategy

fn eq(&self, other: &ShiftStrategy) -> 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 ShiftStrategy
