Struct FiniteTransitionMatrix 

pub struct FiniteTransitionMatrix<S> { /* private fields */ }

A finite state vocabulary and row-stochastic transition matrix.

This is the shared transition representation used by observable Markov models and hidden-state models. State order is caller-owned and retained.

Implementations

impl<S: Eq + Clone> FiniteTransitionMatrix<S>

pub fn new( states: Vec<S>, probabilities: Vec<Vec<f64>>, ) -> Result<Self, TransitionError>

Builds a checked matrix from ordered states and probability rows.

pub fn states(&self) -> &[S]

Returns the ordered finite state vocabulary.

pub fn len(&self) -> usize

Returns the state count and matrix dimension.

pub fn is_empty(&self) -> bool

Returns whether the state vocabulary is empty.

pub fn rows(&self) -> &[Vec<f64>]

Returns all row-stochastic probability rows.

pub fn probability_by_index(&self, from: usize, to: usize) -> Option<f64>

Returns a probability by state indices.

pub fn probability(&self, from: &S, to: &S) -> Option<f64>

Returns a probability by state values.
