Function second_central_difference

pub fn second_central_difference<F>(
    function: F,
    at: f64,
    step: f64,
) -> Result<f64, CalculusError>where
    F: FnMut(f64) -> f64,

Expand description

Approximates the second derivative with a central difference.

§Errors

Returns CalculusError when step is invalid, at is not finite, or sampled evaluations are not finite.
