//! Complete numerical input data for power system problem families.
//!
//! A problem instance is distinct from a source network, matrix projection,
//! solver formulation, and solution. The default build provides index based DC
//! OPF and SCOPF instances and has no workspace dependency beyond `powerio`.
//! Enable `matrix` to derive sparse DC OPF operators from an assembled instance.
