Code Metrics

Description and example of code metrics

When Polyspace® Bug Finder™ analyzes your code, you can choose to calculate statistics about your program. Use the Calculate code metrics (-code-metrics) analysis option to activate code metric checking. To understand the different code metric results and how Bug Finder calculates them, see these reference pages.
