Profiler

Run code and measure execution time to improve performance

Description

The Profiler app enables you to profile your code interactively. Profiling is a way to measure the time it takes to run your code and identify where MATLAB® spends the most time. After you identify which functions are consuming the most time, you can evaluate them for possible performance improvements. You also can profile your code to determine which lines of code do not run. Determining which lines of code do not run is useful when developing tests for your code, or as a debugging tool to help isolate a problem in your code.

Profiler app showing the results from profiling the solvelotka function. The Profiler app shows the results using both a flame graph and a table containing the list of functions called with the times each function took to run.
