Fields

nnz: usize

Total number of non-zero elements

dimensions: (DimensionType, DimensionType)

Matrix dimensions (rows, cols)

sparsity_ratio: Precision

Sparsity ratio (nnz / (rows * cols))

avg_nnz_per_row: Precision

Average number of non-zeros per row

max_nnz_per_row: usize

Maximum number of non-zeros in any row

bandwidth: Option<usize>

Bandwidth of the matrix

is_banded: bool

Whether the matrix has a banded structure

Implementations

impl SparsityInfo

pub fn new(nnz: usize, rows: DimensionType, cols: DimensionType) -> Self

Create sparsity information from basic matrix data.

pub fn is_sparse(&self) -> bool

Check if the matrix is considered sparse (< 10% non-zero).

pub fn is_very_sparse(&self) -> bool

Check if the matrix is very sparse (< 1% non-zero).

Trait Implementations

impl Clone for SparsityInfo

fn clone(&self) -> SparsityInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SparsityInfo

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SparsityInfo

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SparsityInfo

fn eq(&self, other: &SparsityInfo) -> 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 Serialize for SparsityInfo

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
