The following provides information on tools within MATLAB that can help you optimize the performance of your code.
1. The first step is to analyze the performance of your MATLAB code in its current state. The following is a link to the documentation regarding this topic:
In particular, the MATLAB Profiler measures where a program spends time and generates a summary. By using the Profiler, you can determine which commands and which lines of code are taking the longest to execute, and therefore determine where you can focus most of your optimization efforts. To read about how to use the MATLAB Profiler to improve performance, please see the following link:
2. There is a section in the documentation that discusses best practices for writing highly efficient code, including when and how to vectorize, how to preallocate memory for arrays,
3. Multithreading comes default enabled in the most recent version of MATLAB. Common mathematical operations are programmed to make use of multithreading. For a list of the affected functions, see the Related Solution at the bottom of this page.
