Code Profiling in Polyspace Platform User Interface

R2026b

Calculate C/C++ source code coverage with respect to existing tests, calculate execution times

You can calculate C/C++ code coverage, execution time, or memory use in the Polyspace Platform user interface. When you execute tests with coverage, execution profiling or memory profiling enabled, along with test results, you can see how much of your code was covered by the tests, or find bottlenecks in execution time or stack usage.
