Struct ParamsStep 

Source 
pub struct ParamsStep {
    pub m_min: f64,
    pub m_max: f64,
    pub m_safety: f64,
    pub m_first_reject: f64,
    pub h_ini: f64,
    pub n_step_max: usize,
    pub rel_error_prev_min: f64,
}
Expand description

Holds parameters to control the variable stepsize algorithm

Fields§

§m_min: f64

Min step multiplier

0.001 ≤ m_min < 0.5   and   m_min < m_max
§m_max: f64

Max step multiplier

0.01 ≤ m_max ≤ 20   and   m_max > m_min
§m_safety: f64

Step multiplier safety factor

0.1 ≤ m ≤ 1
§m_first_reject: f64

Coefficient to multiply the stepsize if the first step is rejected

m_first_reject ≥ 0.0

If m_first_reject = 0, the solver will use h_new on a rejected step.

§h_ini: f64

Initial stepsize

h_ini ≥ 1e-8
§n_step_max: usize

Max number of steps

n_step_max ≥ 1
§rel_error_prev_min: f64

Min value of previous relative error

rel_error_prev_min ≥ 1e-8
