values: Vec<S>

Implementations

impl<S: Scalar> CsrMatrix<S>

pub fn nnz(&self) -> usize

pub fn spmv_add(&self, x: &DVec<S>, y: &mut DVec<S>)

Sparse matrix-vector product: y += A * x

pub fn spmv(&self, x: &DVec<S>) -> DVec<S>

Sparse matrix-vector product: y = A * x

pub fn get(&self, row: usize, col: usize) -> S

Get element (i, j). O(nnz_row) lookup.

pub fn transpose(&self) -> Self

Transpose to CSR (builds a new CSR of A^T).

pub fn to_dense(&self) -> DMat<S>

Convert to dense matrix.
