Enabling multiple outputs using SIMULINK

Is there anyway I can enable multiple outputs in a model in SIMULINK ? Its like I'm making a subsystem comprising of the blocks In1,Complex to Magnitude-Angle, Out2,Out3. This system allows me to get 2 outputs and similarly if I want to have more outputs I just simply add the Complex to Mag-Angle block to the path.So when I setup Mask for the subsystem I can initialize two outputs. I want to make a drop-down menu (input field) in mask so as to enable the desired outputs, whether it may be 2 or 3 and by doing so only the desired outputs are initialized or active.

I have been following the example mentioned on:

But I'm unable to replicate it for the outputs.

Hi Sultan,

I think you are in the right direction of achieving it. However, you may need to modify the callback code a bit in your case.

You will need to initialize the mask and in the callback corresponding, you need to make use of the "add_block" and "add_line" functions to add the out blocks and connect them to relevant ports. The number of blocks may be dependent on the value you set.
