na_0017: Number of called function levels
The number of levels of sub-functions should be limited, typically
to 3 levels. MATLAB® Function blocks that reside at the Simulink® block
diagram level count as the first level, unless it is simply a wrapper
for an external MATLAB file with a
This includes functions that are defined within the MATLAB block
and those in the separate
Standard utility functions, such as built-in functions like
are not include in the number of levels. Likewise, commonly used custom
utility functions can be excluded from the number of levels.
