Struct DetectorBinResponseMatrix 

pub struct DetectorBinResponseMatrix { /* private fields */ }

Detector-bin probabilities for a fixed instrument response.

Rows correspond to true_energies_ev; columns correspond to consecutive intervals in detector_time_edges_us. Building the matrix evaluates the analytical IC/tabulated bin integrals once. Reusing it during optimization changes only the true-energy sample transmission, not the detector physics.

Only entries whose evaluated probability is strictly greater than zero are stored. This is lossless: there is no numerical cutoff, and every nonzero value returned by the response model is retained. Probability outside the acquisition window is likewise never renormalized into the stored rows — each row’s out-of-window fraction is kept alongside it so Self::apply can report the quantified window loss exactly as two_arm_count_response does (pipeline-map R5·7).

Implementations

impl DetectorBinResponseMatrix

pub fn new( true_energies_ev: &[f64], detector_time_edges_us: &[f64], timing_offset_us: f64, response: &ResolutionFunction, ) -> Result<Self, CountsResponseError>

Build a fixed detector-bin response matrix.

pub fn n_true_energies(&self) -> usize

Number of true-energy quadrature points.

pub fn n_detector_bins(&self) -> usize

Number of measured detector-time bins.

pub fn nnz(&self) -> usize

Number of stored nonzero probabilities.

pub fn storage_bytes(&self) -> usize

Heap bytes used by the compact probability storage.

This excludes the small fixed-size Self value, the per-row window-loss fractions, and allocator overhead.

pub fn row_entries( &self, true_index: usize, ) -> impl Iterator<Item = (usize, f64)> + '_

Stored (detector_bin, probability) pairs for one true-energy row.

pub fn probability(&self, true_index: usize, detector_bin: usize) -> f64

Probability that true-energy row true_index lands in detector bin detector_bin.

pub fn apply( &self, incident_fluence_weights: &[f64], transmission: &[f64], ) -> Result<TwoArmCounts, CountsResponseError>

Apply the fixed response separately to open and sample arms.

Numerically equivalent to two_arm_count_response on the same inputs, including the per-arm acquisition-window loss report.

Trait Implementations

impl Clone for DetectorBinResponseMatrix

fn clone(&self) -> DetectorBinResponseMatrix

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DetectorBinResponseMatrix

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

Formats the value using the given formatter.

impl PartialEq for DetectorBinResponseMatrix

fn eq(&self, other: &DetectorBinResponseMatrix) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
