Struct ResolutionMatrix 

pub struct ResolutionMatrix { /* private fields */ }

Row-stochastic CSR representation of the resolution operator R on a fixed target energy grid.

Built from a ResolutionPlan via ResolutionPlan::compile_to_matrix. Exposed so downstream surrogates (see epic #472) can access the row-local entries R_{i, j} directly for LP / quadrature construction.

Owns a copy of the target energy grid for the same reason ResolutionPlan does: caller-side grid-identity checks and explicit grid-mismatch errors via ResolutionError::MatrixGridMismatch.

Implementations

impl ResolutionMatrix

pub fn len(&self) -> usize

Number of rows (target-grid size) covered by this matrix.

pub fn is_empty(&self) -> bool

True when the matrix covers no target energies.

pub fn nnz(&self) -> usize

Total number of stored entries (structural nnz).

Regular-bracket entries with frac == +0.0 retain a zero-valued contribution at the lo + 1 column to preserve NaN-safety under re-application to spectra with NaN at that column; those stored zeros are counted in this total.

pub fn target_energies(&self) -> &[f64]

Target energy grid the matrix was compiled for.

pub fn row_starts(&self) -> &[u32]

CSR row-start offsets. row_starts()[i]..row_starts()[i+1] names the entry range for row i. Length len() + 1.

pub fn col_indices(&self) -> &[u32]

CSR column indices. Sorted ascending within each row.

pub fn values(&self) -> &[f64]

CSR values. Each row sums to 1.0 to machine precision.

Trait Implementations

impl Clone for ResolutionMatrix

fn clone(&self) -> ResolutionMatrix

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResolutionMatrix

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

Formats the value using the given formatter.
