Nexus - MATLAB Compatible Computing Platform
📊 Setup and Infrastructure - Three-Way Comparison
Comprehensive performance comparison of Phase 1 proprietary implementation versus Original GPL code and MATLAB built-in functions.
Pass column: Pass only when the proprietary time is strictly less than both the GPL and MATLAB times (Phase 6 and other phases). For Phase 4, GPL must be present; MATLAB may be missing (GPL-only reference). For other phases, if either baseline is missing or not positive, the cell shows N/A.

📝 Notes
- Phase 1: Proprietary implementation using
--enable-phase1 - Original GPL: Standard Octave GPL implementation
- MATLAB: Built-in optimized functions (reference)
- All benchmarks run on the same hardware for fair comparison
- Times are average execution time per function call
- Improvement percentage shows Phase 1 vs Original GPL
