Struct SumTangent 

pub struct SumTangent {
    pub k: Complex,
    pub eta: Complex,
    pub shift: [f64; 3],
    pub kpar: [f64; 3],
    pub vectors: [[f64; 3]; 3],
}

A direction in the continuous inputs of a lattice sum.

Geometry components outside the lattice or shift dimension are zero.

Fields

k: Complex

Complex wavenumber direction.

eta: Complex

Complex Ewald-split direction.

shift: [f64; 3]

Cartesian shift direction.

kpar: [f64; 3]

Bloch-wavevector direction in the lattice frame.

vectors: [[f64; 3]; 3]

Row lattice-vector directions in the lattice frame.
