Struct SemiringMatrix

pub struct SemiringMatrix<T> { /* private fields */ }

半環上の行列

Implementations

impl<T: Semiring + Copy> SemiringMatrix<T>

pub fn zero(h: usize, w: usize) -> Self

h×wの零行列を返す。

pub fn unit(n: usize) -> Self

n×nの単位行列を返す。

pub fn transpose(self) -> Self

w×hの転置行列を作る。

pub fn try_mul(self, b: Self) -> Option<Self>

行列積$ab$を求める。

$a$の列数と$b$の行数が一致していないとき、行列積は定義されないので、Noneを返す。

pub fn pow(self, n: u64) -> Self

行列aのn乗を求める。

pub fn get_mut(&mut self, i: usize, j: usize) -> Option<&mut T>

i行j列の要素への可変参照を返す。

pub fn get(&self, i: usize, j: usize) -> Option<&T>

i行j列の要素への参照を返す。

Trait Implementations

impl<T: Clone> Clone for SemiringMatrix<T>

fn clone(&self) -> SemiringMatrix<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for SemiringMatrix<T>

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

Formats the value using the given formatter.

impl<T> Index<usize> for SemiringMatrix<T>

type Output = [T]

The returned type after indexing.

fn index(&self, i: usize) -> &Self::Output

Performs the indexing (container[index]) operation.

impl<T: PartialEq> PartialEq for SemiringMatrix<T>

fn eq(&self, other: &SemiringMatrix<T>) -> 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.
