Struct CsrPattern 

pub struct CsrPattern {
    pub dim: usize,
    pub row_ptr: Vec<u32>,
    pub col_ind: Vec<u32>,
}

Available on crate feature bytecode only.

Compressed Sparse Row (CSR) format for sparse matrices.

Fields

dim: usize

Dimension of the square matrix.

row_ptr: Vec<u32>

Row pointers (length dim + 1). Row i spans col_ind[row_ptr[i]..row_ptr[i+1]].

col_ind: Vec<u32>

Column indices, sorted within each row.

Implementations

impl CsrPattern

pub fn nnz(&self) -> usize

Number of stored entries.

pub fn reorder_values<F: Copy>( &self, coo: &SparsityPattern, coo_vals: &[F], ) -> Vec<F>

Reorder values from COO order (matching SparsityPattern) to CSR order.

Given Hessian values in COO order from sparse_hessian, returns values aligned with this CSR pattern’s col_ind ordering.

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for CsrPattern

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
