num::randommat::exact

Defined in header <linear/graph/randommat/approxchol.hpp>

template <typename Float = double, std::integral Index = num::idx>
cholesky_factor<Float, Index> exact(const adjacency_list<Float, Index> &G);

Exact sparse Cholesky factorization via full star-mesh elimination.

Return value

cholesky_factor: the sparse approximate factor, consumed by randommat::solve.
