Implementations

impl CsrMatrix

pub fn new( rows: usize, cols: usize, row_offsets: Vec<usize>, column_indices: Vec<usize>, values: Vec<f32>, ) -> Result<Self>

Creates a new value.

pub fn from_coo(coo: &CooMatrix) -> Result<Self>

Builds this value from coo.

pub fn rows(&self) -> usize

Returns rows.

pub fn cols(&self) -> usize

Returns cols.

pub fn row(&self, index: usize) -> Result<SparseRow<'_>>

Returns row.

pub fn rows_iter(&self) -> impl Iterator<Item = SparseRow<'_>>

Returns rows iter.

pub fn row_nnz(&self) -> Vec<usize>

Returns the non-zero count for each row.

pub fn density(&self) -> Result<f32>

Returns stored-entry matrix density.

pub fn column_nnz(&self) -> Vec<usize>

Returns the non-zero count for each column.

pub fn row_sums(&self) -> Result<Vec<f32>>

Returns sums of stored values by row.

pub fn column_sums(&self) -> Result<Vec<f32>>

Returns sums of stored values by column.

pub fn summary(&self) -> Result<SparseMatrixSummary>

Returns compact shape, density, row nnz, and column nnz statistics.

pub fn l2_normalize_rows(&self) -> Result<Self>

Returns a CSR matrix whose non-zero rows have unit L2 norm.

pub fn mul_dense_matrix(&self, right: &F32MatrixView<'_>) -> Result<F32Matrix>

Multiplies this CSR matrix by a dense finite matrix.

pub fn to_dense_matrix(&self) -> Result<F32Matrix>

Converts this CSR matrix into a row-major dense matrix.

pub fn mul_dense_vector(&self, vector: &[f32]) -> Result<Vec<f32>>

Multiplies this CSR matrix by a dense finite vector.

pub fn to_coo(&self) -> Result<CooMatrix>

Converts this CSR matrix to COO entries.

pub fn transpose(&self) -> Result<Self>

Returns the matrix transpose.

pub fn validate(&self) -> Result<()>

Validates this value.

Trait Implementations

impl Clone for CsrMatrix

fn clone(&self) -> CsrMatrix

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CsrMatrix

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

Formats the value using the given formatter.

impl PartialEq for CsrMatrix

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