Enum SymmetricRange 

pub enum SymmetricRange {
    All,
    Interval {
        low: f64,
        high: f64,
    },
    Select(Range<usize>),
}

Which eigenvalues lapack_dsyevr computes (igraph_lapack_dsyev_which_t plus its parameters).

Variants

All

All the eigenvalues (IGRAPH_LAPACK_DSYEV_ALL).

Interval

The eigenvalues in the half-open interval (low, high] (IGRAPH_LAPACK_DSYEV_INTERVAL).

Fields

low: f64

Exclusive lower bound.

high: f64

Inclusive upper bound.

Select(Range<usize>)

The eigenvalues with the given zero-based positions in increasing order (IGRAPH_LAPACK_DSYEV_SELECT with one-based il = start + 1, iu = end).

Trait Implementations

impl Clone for SymmetricRange

fn clone(&self) -> SymmetricRange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SymmetricRange

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

Formats the value using the given formatter.

impl PartialEq for SymmetricRange

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