Usage
Add the following to your ‘’‘Cargo.toml’‘’:
[dependencies]
hipparchus-mean = "0.1"
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 |
