Function s_to_t_topp2 

pub fn s_to_t_topp2(
    s: &[f64],
    a: &[f64],
    t0: f64,
) -> Result<(f64, Vec<f64>), CoppError>

Compute cumulative time profile t(s) from a(s).

Semantics

• t_s[i] is the time at station s[i].
• initial condition is t_s[0] = t0.
• returns (t_final, t_s) where t_final == *t_s.last().unwrap().

Input contract

• valid when s.len() >= 2 and a.len() == s.len();
• s, a, and t0 must contain only finite values;
• s must be strictly increasing;
• each interval must have finite positive speed denominator.

Returns

Returns (t_final, t_s) with t_s.len() == s.len() on valid input.

Errors

Returns CoppError::InvalidInput when dimensions, monotonicity, positivity, or numeric finiteness requirements are violated.

Contract

• t_s is monotonically increasing when a is nonnegative and s is increasing.
• t_s[0] == t0 always holds on valid input.
