MATLAB: Is it possible to log all warnings which occur during a simulation in Simulink 7.6 (R2010b)

alllastwarnlogloggingsimulinksllastwarningwarning

During a simulation many different warnings can occur.

Unfortunately LASTWARN only gives me the last occured warning.

I would like to capture all warnings which occured.

The ability to log all occured warnings during a simulation is not available in Simulink.

To work around this you can do the following:

diary on;
sim(<...>);
diary off;

DIARY will create a txt-file which all command line output will be saved in.

After the simulation you can manually check the file and see which warnings occured or do a post-processing to automatically extract the occured warnings.

Try using lastwarn:

% Initialize the global lastwarn variable to "Success"
lastwarn('Success') 
% Some code that may or may not produce an error
a=10;
% Check if a warning was issued.
if strcmp(lastwarn, 'Success')
  % All is well - no warning.
  fprintf('All is well - no warning.\n');
else
  % A warning was issued.
  fprintf('A warning was issued..\n');
end

MATLAB: How to compare two configuration sets in Simulink 7.6 (R2010b)

In order to compare the configuration sets we can first export them to M-files and then use the built in MATLAB Compare functionality, VISDIFF. “Simulink.BlockDiagram.saveActiveConfigSet('model', 'filename')” saves the active configuration set of a model to an M-file.

For example, we can export the configuration set for the shipping demo VDP with the following commands:

>> vdp
>> Simulink.BlockDiagram.saveActiveConfigSet(bdroot, 'filename')

After exporting the two active configuration sets to M-files they can be compared with the following command:

visdiff('fname1', 'fname2')
