Hello everybody,
I am working on a simulink model which should be modified every time an excel file is modified. the idea is to use the getfile checksum function but i can't find a solution to make an automatic check in the model to know if the excel file is modified or not ?
Thanks in advance,

Hi Lamjed,
does the entire Simulink model needs to be changed or only a block? If it's only a block you could mask the block and add to the mask initialization the call to update (or not).
If it is the whole model, you would need to add this to the model init function (menu File->Model Properties->Callbacks->InitFcn).
