Type Alias DiffEq

pub type DiffEq = fn(&NalgebraVec<f64>, &NalgebraVec<f64>, f64, &mut NalgebraVec<f64>, NalgebraVec<f64>, &Covariates);

This closure represents the differential equation of the model.

Parameters

• x: The state vector at time t
• p: The parameters of the model; Use the [fetch_params!] macro to extract the parameters
• t: The time at which the differential equation is evaluated
• dx: A mutable reference to the derivative of the state vector at time t
• rateiv: A vector of infusion rates at time t
• cov: A reference to the covariates at time t; Use the [fetch_cov!] macro to extract the covariates

Example

use pharmsol::*;
let diff_eq = |x, p, t, dx, rateiv, cov| {
 fetch_params!(p, ka, ke, v);
 fetch_cov!(cov, t, wt);
 dx[0] = -ka * x[0];
 dx[1] = ka * x[0] - ke * x[1];
};
