Complexity Analysis
- Time Complexity:
O(mn) - Space Complexity:
O(m + n)
Performance Insight: The time complexity of this algorithm is quadratic matrix (O(mn)), SIMD acceleration or approximate methods are advised when m, n exceed 10⁴.
Note: Complexity analysis is based on theoretical models. Actual runtime is affected by input scale, hardware, and implementation optimizations. Benchmark for your specific workload.
