PreSaveFcn Callback

Asked by Adrian Dronca on 27 Jun 2012
Accepted Answer by TAB

I want to save the model with a different name and get the model name of the previous model.

For example I have a model named 'model_A' and change it to 'model_B'

I set the PreSaveFcn callback, but in this callback i get the name of the new model 'model_B'.

How do i get the information for the old model ? Do I have to use a different callback ?

Thanks in advance, Adrian.

Store the current model name in a variable and then save it with other name.

OldName = bdroot; % ie model_A
save_system(OldName, 'model_B'); save with new name;

yes :( you are right.

Do you know any callback function that is called right before the save ?

Maybe there are some workarounds I can use.

You can do it by saving the model from a m-file as I suggested above.
Create your own Save As option in tool menu of the simulink GUI and call above code in the callback of that option.
