I came across this block in a model but I cannot understand what this block does or what it is called. Could someone help me please.
Thank you in advance!

It looks like the "Fcn" block specified as "u(1)". It is used to pick out the first element.
It was removed in R2020a.
If you can't find it in your release, you can use the Selector block or the DeMux block.

Right click on the block in question. This will bring up a context menu. Select "help" from the bottom of this menu. This will tell you all about the block.
