Function ion_transition_function_midpoint

pub fn ion_transition_function_midpoint(
    midpoint: f64,
    window_length: f64,
    k: f64,
) -> impl Fn(Vec<f64>) -> Vec<f64>

Ion transmission function for quadrupole selection simulation

Arguments:

• midpoint - center of the step
• window_length - length of the step
• k - steepness of the step

Returns:

• impl Fn(Vec<f64>) -> Vec<f64> - ion transmission function

Examples

use mscore::timstof::quadrupole::ion_transition_function_midpoint;

let ion_transmission = ion_transition_function_midpoint(150.0, 50.0, 1.0);
let mz = vec![100.0, 150.0, 170.0];
let transmission = ion_transmission(mz).iter().map(
|&x| (x * 100.0).round() / 100.0).collect::<Vec<f64>>();
assert_eq!(transmission, vec![0.0, 1.0, 1.0]);
