Struct LanczosOptions 

#[non_exhaustive]
pub struct LanczosOptions {
    pub krylov_dimension: usize,
    pub tolerance: f64,
}

Dimension and breakdown tolerance for a Lanczos decomposition.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

krylov_dimension: usize

Maximum number of orthonormal Krylov vectors.

tolerance: f64

Threshold for norm breakdown and Hermiticity checks.

Implementations

impl LanczosOptions

pub const fn new(krylov_dimension: usize) -> Self

Construct a decomposition request with the default breakdown tolerance.

pub const fn with_tolerance(self, tolerance: f64) -> Self

Set the norm-breakdown and Hermiticity tolerance.

Trait Implementations

impl Clone for LanczosOptions

fn clone(&self) -> LanczosOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LanczosOptions

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

Formats the value using the given formatter.

impl PartialEq for LanczosOptions

fn eq(&self, other: &LanczosOptions) -> 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.
