Learn MATLAB vectorization: replace suitable loop-based operations with array and matrix expressions, use built-in functions, preallocate arrays and measure performance. The actual speed improvement depends on the code, data and MATLAB version, so this tutorial focuses on testing rather than promising a fixed multiplier.
In this MATLAB performance tutorial: • Understand vectorised array operations • Replace selected for loops with matrix expressions • Use element-wise operators correctly • Preallocate arrays that still require loops • Compare implementations with timing tools • Keep readable code while improving performance
Chapters: 0:00 Introduction 0:30 What is vectorization? 1:00 Loop versus vectorised comparison 1:30 Built-in functions 2:00 Benchmarking results 2:20 Summary
