Only display warning once (for one time step) in diagnostic viewer

Dear supporters,

i´m currently implementing a NaN/Inf detection in my simulink model. My approach is to do it with the diagnostics and it almost works fine. I enabled the warning for Inf/NaN, but now it outputs 16000 warnings as my model is running in a loop. (One warning for each time step if NaN/Inf was found) Is it possible to avoid that and only get one warning for each Inf/NaN that was found in the whole process (-> avoid the output for each time step?)?

Thanks for your help in advance, if there are further questions, i can clarify the question.

Set some parameter at the start of your code, for example

warning_displayed = false;

Now put an if statement around your warning

if ~warning_displayed
    warning('your warning')
    warning_displayed = true;
end

Does this help?

@Mathias Smeets thanks for your answer, but it doesn't really help. I don´t have any code, as it is only a simulink model. I am actually not that experienced with simulink. Furthermore the warning also includes the timestamp, so your approach wouldn´t work as it is a different text for each warning, even if it´s caused by the same mistake.

Do you have any other ideas?

No I don't know sorry
