Struct DMatrixEntry

pub struct DMatrixEntry {
    pub source_cluster: usize,
    pub field_cluster: usize,
    pub diagonal: Array1<Complex64>,
}

Expand description

D-matrix entry for a far cluster pair

The D-matrix for SLFMM is diagonal (same multipole index in source and field), so we store only the diagonal entries to save memory. This reduces storage from O(n²) to O(n) per cluster pair.

Fields§

§source_cluster: usize

Source cluster index

§field_cluster: usize

Field cluster index

§diagonal: Array1<Complex64>

Diagonal translation coefficients (length = num_sphere_points) The full D-matrix would be: D[p,q] = diagonal[p] if p == q, else 0
