Struct PartialUtils 

pub struct PartialUtils;

Utility functions for partial derivatives

Implementations

impl PartialUtils

pub fn expressions_equal(expr1: &Expression, expr2: &Expression) -> bool

Fast expression equality check with caching

Examples

use mathhook_core::simplify::Simplify;
use mathhook_core::calculus::derivatives::PartialUtils;
use mathhook_core::calculus::derivatives::MatrixUtils;
use mathhook_core::{Expression};
use mathhook_core::symbol;

let x = symbol!(x);
let expr1 = Expression::symbol(x.clone());
let expr2 = Expression::symbol(x.clone());
let equal = PartialUtils::expressions_equal(&expr1, &expr2);

pub fn is_zero(expr: &Expression) -> bool

Fast zero check with pattern matching

Examples

use mathhook_core::calculus::derivatives::PartialUtils;
use mathhook_core::Expression;

let zero = Expression::integer(0);
let is_zero = PartialUtils::is_zero(&zero);

pub fn validate_dimensions( name: &str, expected: usize, actual: usize, ) -> Result<(), String>

Validate dimension compatibility early

Examples

use mathhook_core::calculus::derivatives::PartialUtils;
let result = PartialUtils::validate_dimensions("gradient", 3, 3);
assert!(result.is_ok());
