MO-POWFEM V5 — MATLAB codes for weighted FEM double-phase degenerate problems

This deposit contains two MATLAB scripts associated with the paper "A Weighted Finite Element Method for Double-Phase Degenerate Problems in Musielak–Orlicz Spaces": MO_POWFEM_V4.m — Main simulation code producing the numerical results of Section 8 (convergence rates, conditioning, asymptotically diagonal Gram decomposition, Tests 1–3). complexity_benchmark_standalone.m — Benchmark script producing Table 1 and Figure 1 of Section 4.4 (local computational complexity comparison: MO-Jacobi diagonal basis vs. standard nodal tensor-product basis, measured via MATLAB's timeit on batches of 500 independent solves per data point, Case C, α=−0.3, h=1/32, k=1,...,8). Both scripts are self-contained and run in MATLAB (tested in MATLAB Online) without additional toolboxes.
