gtopt/lp_stats.hpp file

Static analysis of LP coefficient matrices for numerical conditioning diagnostics.

Provides ScenePhaseLPStats and log_lp_stats_summary() — a lightweight reporting facility that logs min/max absolute coefficient, ratio, and conditioning quality per scene/phase. When the global coefficient ratio is below a configurable threshold the output is a single summary line; otherwise a per-scene/phase table is printed.

The actual min/max/nnz values are computed inside LinearProblem::flatten() when LpMatrixOptions::compute_stats is true, and stored in the FlatLinearProblem struct.
