Hi Arepalli,
To add a new "Bus Creator" block with "n" number of Inputs, you can pass an additional name-value parameter in the "add_block" function as follows:
>> add_block("simulink/Commonly Used Blocks/Bus Creator","testing_bus/Bus Creator", "Inputs", "5");
This will create a Bus Creator block named "Bus Creator" with 5 input ports.
Similarly, to edit the number of ports in an existing block, you can pass this "Inputs" name-value parameter to the "set_param" function for a given block.
>> set_param("path_to_block", "Inputs", "7");
