Hello all,

I am creating a custom library block for my project which I followed mask concept as Unit delay block. However, I got some difficulties on creating New data for my state variable. Currently, I can only create a state variable which will be stored in data dictionary by default; however, I would like to create as following Unitdelay concept. But I could not find any documents which introduced how to do these stuffs for custom library block.

Or whether are there any Parameter options available for creating this on Mask Editor? Please give me some hints here. Thank you so much!

Anyway, thank you for addressing here. I am still finding some sources which introduce that but there is nothing so far. Not sure Mathworks supports to manupilate it programatically.

Create a Mask for your customized library block, then when you double click the block, you will have a dialog to specify that parameter, just like the dialog you got when double click the UnitDelay block. The built-in "three dot action button" always appears on the side. Click the button and you will see the "Create variable" or "ParameterName: Create ..." option.
