• Version 6.0

Sub ID Recommendations

• NA-MAAB — a

• JMAAB — a

MATLAB Versions

All

Rule

Sub ID a

Data names defined within MATLAB functions shall not use underscores at the end.

Custom Parameter

Not Applicable

Sub ID b

Consecutive underscores shall not be used in data names defined within MATLAB functions.

Custom Parameter

Not Applicable

Sub ID c

Data names defined within a MATLAB functions shall not be the same as reserved MATLABwords.

Custom Parameter

Not Applicable

Rationale

Sub ID a:

• Deviation reduces readability. Since underscores are commonly used as word separators, it may look like a typographical error.

Sub ID b:

• Deviation reduces readability.

Sub ID c:

• Deviation reduces readability.

• Deviating from common practices may lead to unexpected problems.

Note

The MATLAB limit for the number of characters you can use in data names defined within MATLAB functions is 2048.
