Use five practical MATLAB techniques to improve performance and readability: vectorization, preallocation, built-in functions, logical indexing and the Profiler. Results vary by workload, so measure before and after instead of assuming every change is faster.
The five MATLAB tips: 1. Vectorise suitable array operations 2. Preallocate arrays that grow inside loops 3. Use clear built-in functions 4. Filter data with logical indexing 5. Find real bottlenecks with the Profiler
