Using Matlab, how would I write a script that adds 1 every time I hit run? For example: first run x=1, second run x=2, and so on. I'm doing this for a true/false script. If my value returns true, I want to index a 0+1 into a "yes" variable. If false, it'll index a 0+1 into "no", if true again, then 1+1 and so on.
