Trait Submatrix

pub trait Submatrix<O>: Matrix
where
    O: Matrix,
{
    type Index;

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

Required Associated Types

type Index

Required Methods

fn submatrix(&self, index: Self::Index) -> O

Returns 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 s = [
    [5.0, 6.0],
    [8.0, 9.0]
];
assert_eq!(a.submatrix((0, 0)), s);

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.
