How to find the warning identifier from a warning message?

Hi everyone,

I have a warning message in Simulink and I am looking to find the warning message identiier. So, that I can add to a list of identifiers in my code which need to be ignored during the build process. Could someone tell me is there any way to find the warning identifier of a particular warning message? or does Simulink have any documentations, where it provides list of all possible errors and warnings with their identifiers?

This is my warning message: ''Warning: Unable to honor user-specified priorities''

Thank you in Advance!!

In Matlab itself you can use [msg,msgID] = lastwarn; to retrieve the warning ID. I don't know if there is an easy way to retrieve this in Simulink. Running that function in Matlab might work.

@Rik Thanks for your reply. I already tried above command. It works only when simulink generates the warning. In my case, I just have the warning message and I don't know where and when it occurs. I need to find the identifier and add this to the another file, which ignores this warning during build process.

'Simulink:Engine:UnableToHonorPriority'

I searched the .xml message files using Unix commands.

cd(matlabroot)
!find . -depth -name \*.xml -print0 | xargs -0 egrep -i "Unable to honor user-specified priorities"

@Walter Roberson I tried on my PC using cmd prompt by changing the directory to Matlab and using the same command as described above, but I am getting some error message. Usually identifiers are defined by single colon, for example MATLAB:UndefinedFunction. So, for my warning message, is the entire thing 'Simulink:Engine:UnableToHonorPriority' is identifier or only 'Simulink:Engine'?

>> warning(message('Simulink:Engine:UnableToHonorPriority', 'A', 1, 'B', 2))
Warning: Unable to honor user-specified block priorities. 'A' with a block priority 1 has to execute before 'B' that has a higher block priority 2 to
satisfy data dependencies. 

There can be any number of colons in the name. Each one except the last corresponds to a subdirectory within fullfile(matlabroot, 'resources') with the major product being followed by the language code, and with the final token appearing as a key in the xml file. For example

./resources/Simulink/en/Engine.xml:
<entry key="UnableToHonorPriority">Unable to honor user-specified priorities. ''{0}'' (pri={1}) has to execute before ''{2}'' (pri={3}) to satisfy data dependencies</entry>

or

>> warning(message('optim:algorithm:checkInitialPoint:WrongSizeX0'))
Warning: x0 must have the same number of elements as f, or as the number of columns of A or Aeq. 

corresponding to resources/optim/en/algorithm/checkInitialPoint.xml key WrongSizeX0

Yes, I agree with you. I also found the xml you are referring to. Thank you very much!!
