pub fn build_ptdf_lodf(
case: &IndexedNetwork<'_>,
conv: DcConvention,
) -> Result<(CsMat<f64>, CsMat<f64>)>Expand description
Both DC sensitivity matrices (PTDF, LODF) from a single Laplacian
factorization. When a caller needs both for the same case (the
sensitivities bundle), this factors and inverts the grounded Laplacian
once instead of paying the O(n³) twice across separate
build_ptdf/build_lodf calls.
