Hello. I have the matrix [1;1]. How do I use the selector block to extract the first element only? I tried going to the page for the block but it went over my head. Sorry if this is a basic question.

Hi,
A selector block is one which selects the input based on the parameter set in the block. To get the first element of the input you are passing, you need to select the parameter “Index Option” as Index Vector(dialog) and then specify which index of input has to be selected and set even the other parameters of selector block appropriately.
