Hi Mehrad,
One of the way using which you can bring the excel data into the Simulink is by using Signal builder block. you can add the following sample code in the 'PostLoadFcn' callback in the Model properties:
[num,txt] = xlsread('test_data');
block = signalbuilder('test/Signal Builder', 'append', num(:,1), num(:,2), '');
Where ‘test_data’ is the name of the Excel file and ‘test’ is the name of the Simulink model file. When you open the model with the signal builder block, follow the below steps:
1) Navigate to File>Model Properties.A dialog box opens up.
2) Go to CallBacks tab and click on PostLoadFcn. Paste the above mentioned code. Placing the code in the PostLoadFcn callback means that the code is executed whenever the model is loaded and therefore you will find two signal groups already present in the signal builder block.
3) To confirm that the above code works correctly, delete the second signal group, save the model, close and then reopen the model. The two signal groups should again be present in the signal builder block.
The above code appends a signal group with one signal into the signal builder block. It can be modified to add more than one signals. Hope this helps!
