pub fn work_from_force_samples(
displacements: &[f64],
forces: &[f64],
) -> Option<f64>Expand description
Approximates work from aligned force and displacement samples.
Formula: W = Σ(F_i * d_i)
Returns None when the slice lengths differ, when any value is not finite, or when the
computed result is not finite. Returns Some(0.0) for two empty slices.
