Example

Lp Norm

Here's an example to calculate L1 norm of a vector via hipparchus:


use hipparchus_mean::LpNorm;

let v = vec![1.0, 2.0, 3.0, 4.0, 5.0];
let norm = v.iter().l0norm().unwrap();

Below is a full list of all norm algorithms hipperchus has supported:

Norm Syntax Feature
l0norm - L0 norm
l1norm - L1 norm
l2norm - L2 norm
lpnorm (f32) Lp norm with p factor
lpnorm_inf - Lp norm (p=inf)

Mean & Moving Average

Here's an example to calculate the arithmetic mean of a vector via hipparchus:


use hipparchus_mean::Mean;

let v = vec![1.0, 2.0, 3.0, 4.0, 5.0];
let mean = v.iter().arithmetic_mean().unwrap();

Below is a full list of all mean algorithm hipperchus has supported:

Mean Syntax Feature
ArithmeticMean - arithmetic mean
GeometricMean - geometric mean
QuadraticMean - quadratic mean
HarmonicMean - harmonic mean
SimpleMovingAverage - simple moving average
CumulativeMovingAverage - cumulative moving average
WeightedMovingAverage - weighted moving average
ExponentialMovingAverage (f32) exponential moving average with decay
