Suppress Warning Messages

Is there a way to suppress the "Warning: Visualization blocks are not updated during command line simulation in rapid accelerator mode." messages?

The visualisation blocks are useful when running my model from Simulink so I don not want to delete them but I don't wand to receive the errors when running from the command line.

Thanks

Mike

You can use

warning('off','message_id')

to turn off a specific warning. You can use lastwarn to find out the message_id corresponds to the visualization block warning. Details can be found in the doc

Thanks for your help.

One additional point for others who may want to use this solutions is that I had to use '[msgstr, msgid] = lastwarn' to get the message_id as lastwarn only repeats the error message.

Here's a well-commented snippet of my code that you may find helpful. I used it to suppress an Excel informational message.

% Turn off note "Warning: Added specified worksheet." 
% that appears in the command window.
% To set the warning state, you must first know the 
% message identifier for the one warning you want to enable. 
% To get that, query the last warning to acquire the identifier.
% For example: 
% warnStruct = warning('query', 'last');
% msgid_integerCat = warnStruct.identifier
% Command window will show this:
% msgid_integerCat =
%    MATLAB:xlswrite:AddSheet
% You need to pass the expression with the colons in it into the warning() function.
% Turn off note "Warning: Added specified worksheet." that appears in the command window.
warning('off', 'MATLAB:xlswrite:AddSheet');

Is this warning-off status temporary or permanent? If I type it into the command window just one time, will it forever after suppress that particular warning? Or is it reset after restarting Matlab? Or when does it get reset?

It's just for that session. If you want to suppress them permanently, you can call my attached TurnOffWarnings() function from your startup.m file. Modify it for additional warnings that you encounter that you'd with to suppress.
