Struct yata::methods::Derivative [−][src]
pub struct Derivative { /* fields omitted */ }
Expand description
Derivative of specified window length
for timeseries of ValueType
Parameters
Has a single parameter length
: PeriodType
length
should be > 0
Default is 1
Input type
Input type is ValueType
Output type
Output type is ValueType
Examples
use yata::prelude::*; use yata::methods::Derivative; let s = vec![0.0, 1.0, 3.0, 0.5, 2.0, -10.0]; let r = vec![0.0, 1.0, 2.0,-2.5, 1.5, -12.0]; let mut derivative = Derivative::new(1, s[0]).unwrap(); (0..s.len()).for_each(|i| { let der = derivative.next(s[i]); assert_eq!(der, r[i]); });
