Implementations§

Source §

impl SparseTriplet

Source

pub fn new() -> Self

Create an empty triplet store.

Source

pub fn add(&mut self, row: usize, col: usize, val: f64)

Push a single entry (row, col, val).

Source

pub fn to_csr(&self, n_rows: usize, n_cols: usize) -> CsrMatrix

Convert to CsrMatrix, sorting by (row, col) and summing duplicates.
