Simulink turn off data logging
显示 更早的评论
Hello ! I do have the following problem: I have a very big simuling model, with a lot of subsystems. In this model a lot of signal have already logged. I'm making a test environment to run this model, and I have to test the result of the simulation. I have to log only a few data, but in the model there are approximately 150 logged signal (and it's made the simulation much slower). So for that, in my test environment I'd like to unlog all of the signal, and turn on only witch are necessary for me.

Disable all logging at once
% Find all ports with data logging enabled
pH = find_system('YourModelName', 'FindAll', 'on', 'Type', 'Port', 'DataLogging', 'on');
% Disable all logging
for x=1:length(pH)
set_param(pH(x), 'DataLogging', 'off');
end

I had a similar issue, I ended up modifying to this though:-
pH = find_system('Your Model name','LookUnderMasks','all','FindAll', 'on', 'DataLogging', 'on');
'Type', 'Port'
Having type and port in the search misses other potentially logable terms.

Turn this model into .mdl format
Open model in text
Find all "datalogging on", set it to off
Done!

this command works in a better way！
set_param(bdroot, 'InstrumentedSignals', [])
