Types of Coverage Reports

External MATLAB File Coverage Report
If your top-level model calls any external MATLAB files, select Coverage for MATLAB
files on the Coverage tab of the Coverage Settings dialog box. The software creates
a report, named MATLAB_file_name_cov.html, for each distinct file called from the
model. When there are several calls to a given file from the model, the software creates
only one report for that file, but it accumulates coverage from all the calls to the file. The
external MATLAB file coverage report does not include information about what parts of
the model call the external file.
The first section of the external MATLAB file coverage report contains summary
information about the external file, similar to the model coverage report.
