pub fn geometry_cofactor(
los: &[LineOfSight],
weights: &[f64],
receiver: Wgs84Geodetic,
) -> Result<GeometryCofactor, DopError>Expand description
Compute the single-clock geometry cofactor matrix from line-of-sight rows.
This exposes the same cofactor matrix that dop uses internally:
Q = (H^T W H)^-1, with H rows [-e_x, -e_y, -e_z, 1]. The inverse is the
deterministic 4x4 cofactor expansion used by the 0-ULP DOP parity tests.
