Struct Monomial 

pub struct Monomial {
    pub powers: Vec<(usize, usize)>,
}

A monomial: product of variables with powers Represented as sorted list of (variable_index, power)

Fields

powers: Vec<(usize, usize)>

(variable_index, power) pairs, sorted by variable index

Implementations

impl Monomial

pub fn one() -> Self

Create constant monomial (1)

pub fn var(i: usize) -> Self

Create single variable monomial x_i

pub fn new(powers: Vec<(usize, usize)>) -> Self

Create from powers (will be sorted)

pub fn degree(&self) -> usize

Total degree

pub fn is_constant(&self) -> bool

Is this the constant monomial?

pub fn max_var(&self) -> Option<usize>

Maximum variable index (or None if constant)

pub fn mul(&self, other: &Monomial) -> Monomial

Multiply two monomials

pub fn eval(&self, x: &[f64]) -> f64

Evaluate at point

pub fn divides(&self, other: &Monomial) -> bool

Check divisibility: does self divide other?

Trait Implementations

impl Clone for Monomial

fn clone(&self) -> Monomial

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Monomial

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

Formats the value using the given formatter.

impl Display for Monomial

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

Formats the value using the given formatter.

impl Eq for Monomial

impl Hash for Monomial

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Monomial

fn eq(&self, other: &Monomial) -> 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.
