Struct SparseGBlock 

pub struct SparseGBlock {
    pub row_off: usize,
    pub col_off: usize,
    pub data: Array2<f64>,
}

One co-occurring atom-pair block of a block-sparse left factor A.

data is the dense (m_i × m_j) coupling between the basis columns of atom i (rows, starting at left-factor offset row_off) and atom j (columns, starting at col_off). Both offsets are in left-factor (A) coordinates, i.e. μ-space, not β-space.

Fields

row_off: usize

Left-factor (μ-space) row offset = beta_offset[atom_i] / p.

col_off: usize

Left-factor (μ-space) column offset = beta_offset[atom_j] / p.

data: Array2<f64>

Dense (m_i × m_j) coupling block.
