Struct yata::methods::HighestLowestDelta
source · pub struct HighestLowestDelta { /* private fields */ }
Expand description
Calculates absolute difference between highest and lowest values over the last length
values for timeseries of type ValueType
§Parameters
Has a single parameter length
: PeriodType
length
should be > 0
§Input type
Input type is ValueType
§Output type
Output type is ValueType
Output value is always >= 0.0
§Examples
use yata::prelude::*;
use yata::methods::HighestLowestDelta;
let values = [1.0, 2.0, 3.0, 2.0, 1.0, 0.5, 2.0, 3.0];
let r = [0.0, 1.0, 2.0, 1.0, 2.0, 1.5, 1.5, 2.5];
let mut hld = HighestLowestDelta::new(3, &values[0]).unwrap();
(0..values.len()).for_each(|i| {
let v = hld.next(&values[i]);
assert_eq!(v, r[i]);
});
§Performance
O(length
)
This method is relatively very slow compare to the other methods.
