Struct Ramp 

pub struct Ramp<S: Scalar> {
    pub start_value: S,
    pub end_value: S,
    pub start_time: S,
    pub end_time: S,
}

Linear ramp signal.

Returns 0 before start, ramps linearly from start to end, then returns final value after end.

Example

use numra_core::signal::{Signal, Ramp};

let ramp: Ramp<f64> = Ramp::new(0.0, 2.0, 1.0, 3.0);  // from 0 to 2 between t=1 and t=3
assert!(ramp.eval(0.5).abs() < 1e-10);      // Before ramp
assert!((ramp.eval(2.0) - 1.0).abs() < 1e-10);  // Midpoint
assert!((ramp.eval(4.0) - 2.0).abs() < 1e-10);  // After ramp

Fields
