Hi, Is there any way to write all warnings and errors ocurred in simulation\calculation to some text file?
I generate simulink model automatically and the simulating it through COM. I need to have all errors and warnings occured during simulation in one file.
Thanks in advance,
Tomas

I use a dedicated function for logging warnings and errors: The functions is used instead of WARNING and ERROR and writes all messages in a file, which is opened once at the beginning. Unexpected errors have to be caught by TRY/CATCH then.
function myLog(Command, Caller, Msg)
persistent FID
switch Command
case 'open'
FID = fopen(Caller, 'w');
case 'close'
fclose(FID);
FID = -1;
case 'warning'
fprintf(FID, 'warning: %s: ', Caller);
if iscellstr(Msg)
Msg = sprintf(FID, '%s\n', Msg{:});
Msg(end) = [];
end
fprintf(FID, '%s\n', Msg);
% Perhapse: warning([Caller, ': ', Msg])
% or: fprintf(2, '%s\n', Msg);
case 'error'
fprintf(FID, 'error: %s: ', Caller);
if iscellstr(Msg)
Msg = sprintf('%s\n', Msg{:});
Msg(end) = []; % Remove trailing line break
end
fprintf(FID, '%s\n', Msg);
% Perhaps: error([Caller, ': ', Msg])
% or: fprintf(2, '%s\n', Msg);
end
Now this creates the messages:
myLog('open', fullfile(tempdir, 'logfile.txt'));
myLog('warning', 'Project 1', 'totally nonsense');
myLog('error', 'Project 1', {'Completely', 'wrong'});
myLog('close');
