Function dot
Source pub fn dot(backend: ComputeBackend, a: &Field<f64>, b: &Field<f64>) -> f64
Expand description
Inner product of two scalar fields, sum_i a[i]*b[i].
The Krylov-solver inner product, and — with cell volumes as b — the
volume-weighted integral. Units multiply: [a]*[b].
§Panics
Panics if a.len() != b.len().
§Determinism
Same guarantee as sum.
