Check Bug Reports for Issues and Fixes
Software is inherently complex and is not free of errors. The output of a code generator might contain
bugs, some of which are not detected by a compiler. MathWorks reports critical known bugs brought
to its attention on its Bug Report system at www.mathworks.com/support/bugreports/. In the search
bar, type the phrase "Incorrect Code Generation" to obtain a report of known bugs that produce code
that might compile and execute, but still produce wrong answers. To save a search, click Save
Search.
The bug reports are an integral part of the documentation for each release. Examine periodically all
bug reports for a release, as such reports may identify inconsistencies between the actual behavior of
a release you are using and the behavior described in this documentation.
In addition to reviewing bug reports, you should implement a verication and validation strategy to
identify potential bugs in your design, code, and tools.
