Implementations§

Source§

impl SymbolicExpressionSimplifier

Source

pub fn new() -> Self

Create a new simplifier with the default configuration and built-in rules.

Source

pub fn with_config(config: SesSimplifierConfig) -> Self

Create a new simplifier with a custom configuration.

Source

pub fn add_rule(&mut self, rule: SesRewriteRule)

Add a custom rewrite rule.

Source

pub fn simplify(&mut self, expr: &SesExpr) -> SesExpr

Simplify expr using multi-pass rewriting until fixpoint or max_passes.

Source

pub fn evaluate( &mut self, expr: &SesExpr, vars: &HashMap<String, f64>, ) -> Result<f64, SesError>

Evaluate expr numerically given variable bindings.

Source

pub fn differentiate(&mut self, expr: &SesExpr, var: &str) -> SesExpr

Compute the symbolic derivative of expr with respect to var.

Source

pub fn substitute( &self, expr: &SesExpr, var: &str, replacement: &SesExpr, ) -> SesExpr

Substitute all occurrences of var in expr with replacement.

Source

pub fn contains_var(&self, expr: &SesExpr, var: &str) -> bool

Returns true if expr contains the variable var.

Source

pub fn collect_vars(&self, expr: &SesExpr) -> HashSet<String>

Supports: numbers, identifiers (variables), +, -, *, /, ^, unary -, and function calls sin, cos, exp, ln, sqrt, abs. Parentheses and |...| for absolute value are also supported.

Source

pub fn simplifier_stats(&self) -> SesSimplifierStats

Return current simplifier statistics.

Source

pub fn history(&self) -> &VecDeque<SesSimplificationStep>

Source

pub fn config(&self) -> &SesSimplifierConfig
