Struct YBusSparse 

pub struct YBusSparse { /* private fields */ }

A finalized, frozen Y-bus: consolidated per-row admittance neighbors (for sparse-aware assembly of the linear initial guess and the Jacobian) plus a ready-to-use sparse matrix (for power_injections’s mat-vec, needed every Newton-Raphson iteration). Built once via YBus::finish.

Implementations

impl YBusSparse

pub fn n(&self) -> usize

pub fn row(&self, i: usize) -> &[(usize, Complex<f64>)]

The (col, value) pairs for row i’s actual admittance neighbors (including the diagonal), sorted by column index.

pub fn get(&self, i: usize, j: usize) -> Complex<f64>

The value at (i, j), or zero if there’s no entry there.

pub fn mul_vec(&self, v: &[Complex<f64>]) -> Vec<Complex<f64>>

Trait Implementations

impl Clone for YBusSparse

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
