Struct Erf 

pub struct Erf {}

Vectorized error function (erf).

The implementation uses an approximation from Abramowitz and Stegun, see https://en.wikipedia.org/wiki/Error_function#Approximation_with_elementary_functions.

This has a maximum absolute error of 6.631017e-7 when comparing to libm::erff as a source of truth.

Trait Implementations

impl Default for Erf

fn default() -> Erf

Returns the “default value” for a type.

impl SimdUnaryOp<f32> for Erf

fn eval<I: Isa>(&self, isa: I, x: I::F32) -> I::F32

Evaluate the unary function on the elements in x.

fn apply<I>(isa: I, x: <T as GetSimd>::Simd<I>) -> <T as GetSimd>::Simd<I>

where I: Isa, Self: Default,

Evaluate the unary function on elements in x.

fn map<'dst>( &self, input: &[T], output: &'dst mut [MaybeUninit<T>], ) -> &'dst mut [T]

where Self: Sized, T: GetNumOps,

Apply this function to a slice.

fn map_mut(&self, input: &mut [T])

where Self: Sized, T: GetNumOps,

Apply a vectorized unary function to a mutable slice.

fn scalar_eval(&self, x: T) -> T

where Self: Sized, T: GetNumOps,
