ArrayTrait - Array Linalg Norms functions

Required Methods

fn norm( &self, ord: Option<impl NormOrdType>, axis: Option<Vec<isize>>, keepdims: Option<bool>, ) -> Result<Array<N>, ArrayError>

Calculates matrix or vector norm

Arguments

• ord - order of the norm: {non-zero int, inf, -inf, fro, nuc}. optional
• axis - axis along which vector norms are to be calculated. optional
• keepdims - if true, the result will broadcast correctly against the input. optional

Examples

use arr_rs::prelude::*;

let array_a = Array::arange(-4., 4., None);
let array_b = array_a.reshape(&[3, 3]);

let expected = Array::single(7.745966692414834);
assert_eq!(expected, array_a.norm(None::<NormOrd>, None, None));
assert_eq!(expected, array_b.norm(None::<NormOrd>, None, None));

Errors

may returns ArrayError

fn det(&self) -> Result<Array<N>, ArrayError>

Compute the determinant of an array

Examples

use arr_rs::prelude::*;

assert_eq!(Array::single(-14), Array::new(vec![3, 8, 4, 6], vec![2, 2]).det());

Errors

may returns ArrayError

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.
