Trait Minor

pub trait Minor: Matrix {
    type Index;
    type Output;

    // Required method
    fn minor(&self, index: Self::Index) -> Self::Output;
}

Required Associated Types

type Index

type Output

Required Methods

fn minor(&self, index: Self::Index) -> Self::Output

Returns the determinant of the submatrix of a given cell

|Mᵢⱼ|

Arguments

• index - Row and/or collumn to neglect

Examples

let a = [
    [1.0, 2.0, 3.0],
    [4.0, 5.0, 6.0],
    [7.0, 8.0, 9.0]
];
let m = [
    [5.0, 6.0],
    [8.0, 9.0]
].det();
assert_eq!(a.minor((0, 0)), m);

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementations on Foreign Types

impl<F, const N: usize> Minor for [[F; N]; N]

where Self: Submatrix<[[F; { _ }]; { _ }], Index = (usize, usize)>, [[F; { _ }]; { _ }]: Det,

type Index = <[[F; N]; N] as Submatrix<[[F; { _ }]; { _ }]>>::Index

type Output = <[[F; { _ }]; { _ }] as Det>::Output

fn minor(&self, index: Self::Index) -> Self::Output
