Trait Trace

pub trait Trace: SquareMatrix {
    type Output;

    // Required method
    fn trace(&self) -> Self::Output;
}

Required Associated Types

type Output

Required Methods

fn trace(&self) -> Self::Output

Returns the trace of a given matrix

tr(A)

Examples

let a = [
    [1.0, 2.0, 3.0],
    [4.0, 5.0, 6.0],
    [7.0, 8.0, 9.0]
];
let t = a[0][0] + a[1][1] + a[2][2];
assert_eq!(a.trace(), t);

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> Trace for [[F; N]; N]

where Self: SquareMatrix, F: Add<F, Output = F> + Clone + Zero,

type Output = F
