How can we write data from mat file to Simulink data dictionary.

I am learning MBD. In that I have to initialise many ports and constants with specific name in sldd file. Problem here is that my data is in the xlsx file which I am importing it to workspace and then storing it as .mat file as sldd has only option to read .mat or .m files.

When I do that it throws me message that reads: 0 items were successfully imported.

I have two things to ask:

1) Why no items are successfully imported and

2) what is correct procedure to import data from .mat or .m file to sldd file

Attach here is the xlsx file which has all the names of the port

I have to ask, these signal definitions, for things like 'In8', 'In10', 'Out5', 'Out6'. What are these? Are these signal definitions for the in- and outports of various subsystems in your model?

Why do you want to write all this meta data in an Excel file and then load it into your modeling structure?

Yes they are signal definitions for in and out ports. I mentioned that I am learning MBD and I got the assignement in which we have been provided this file (xlsx) and asked to add the this signal names in sldd file.

Hi Akshay,

You can read the excel file as a table using the "readtable" function: https://www.mathworks.com/help/matlab/ref/readtable.html

Once you have the data, you can write a script which can store the data to the sldd programmatically. Kindly refer to the following article for a better understanding: https://www.mathworks.com/help/simulink/ug/store-data-in-dictionary-programmatically.html
