MATLAB: How to permanently disable a specific warning that M-Lint generates

analyzercodeMATLABmlint

I would like to tell M-Lint to stop generating a specific error message for all my programs.

Best Answer

The ability to set system-wide preferences for M-Lint warnings and errors was added in MATLAB 7.3 (R2006b). These may be set in the general preferences by selecting from the MATLAB desktop 'File->Preferences...' and clicking on the 'M-Lint' node.

For previous versions, you may disable M-Lint warnings and errors on a specific line of MATLAB code. To do this, add the "%#ok" token to the end of the line with the warning to force M-Lint to skip checking the line of code.

MATLAB: How to suppress warnings in the deployed application in MATLAB Compiler 4.17 (R2012a)

You can suppress the warning in your compiled application by adding the following lines of code in startup.m

if isdeployed
      warning off
end

This will turn off all warnings in a compiled application.

You can also use the -w compiler switch to turn individual warnings on and off:

>> mcc -m -w off:MATLAB:dispatcher:nameConflict foo.m

For example, to turn off this particular warning, you can use the warning code: ToolboxPathCache:PathdefNotFound by:

>> mcc -m -w off:ToolboxPathCache:PathdefNotFound foo.m

You can also turn this warning off in the startup.m by appending the following lines of code:

if isdeployed
      warning off ToolboxPathCache:PathdefNotFound
end

MATLAB: Confusing m-lint behaviour after catch statement

Hi,

the code analyzer has some dilemma here: the reason he tells you about the exception object is to make the programmer aware of using the object is much better then the previous lasterr constructs. I guess the optimal solution would be: complain about missing identifier ME only if the user uses lasterr or similar in the catch block, otherwise not. For now he just always complains...

Since you know about the exception objects, you might just turn off the warning in the preferences or do like cyclist does, just suppress ...
