Struct CsrMatrix 

pub struct CsrMatrix<F: Float> {
    pub indptr: Vec<usize>,
    pub indices: Vec<usize>,
    pub data: Vec<F>,
    pub n_rows: usize,
    pub n_cols: usize,
}

Fields

indptr: Vec<usize>

indices: Vec<usize>

data: Vec<F>

n_rows: usize

n_cols: usize

Implementations

impl<F: Float> CsrMatrix<F>

pub fn from_triplets( n_rows: usize, n_cols: usize, triplets: Vec<(usize, usize, F)>, ) -> Self

Build from a list of (row, col, value) triplets. Triplets do not need to be sorted; this constructor sorts within each row by column. Duplicate (row, col) entries are summed.

pub fn nnz(&self) -> usize

pub fn density(&self) -> f64

pub fn row_iter(&self, i: usize) -> impl Iterator<Item = (usize, F)> + '_

Iterate non-zeros of row i as (col, value) pairs.

pub fn to_dense(&self) -> Array2<F>

pub fn matvec(&self, x: &[F]) -> Vec<F>

Sparse-dense matrix-vector multiply: y = A x. Returns a dense vector of length n_rows.

Trait Implementations

impl<F: Clone + Float> Clone for CsrMatrix<F>

fn clone(&self) -> CsrMatrix<F>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<F: Debug + Float> Debug for CsrMatrix<F>

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

Formats the value using the given formatter.

impl<'de, F> Deserialize<'de> for CsrMatrix<F>

where F: DeserializeOwned + Float,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<F> Serialize for CsrMatrix<F>

where F: Serialize + Float,

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
