Function dot_field 

pub fn dot_field(
    backend: ComputeBackend,
    a: &Field<Vector3>,
    b: &Field<Vector3>,
) -> Field<f64>

Element-wise dot product of two vector fields → scalar field: c[i] = a[i] . b[i].

Units multiply: [a]*[b]. Bit-identical to Field::dot_field.

Panics

Panics if a.len() != b.len().
