I want to select certain rows from a list by using two nested Select commands
Select[List1, #[[2]] >=
Select[List2, #[[1]] == IntegerPart[2* PREVIOUS#[[1]] ]/2 &] &]
where by PREVIOUS#[[1]] I mean the first argument of the previous pure function (i.e. the argument of the list List1). I think this question may be duplicated, since I found that people solves this kind of problems using Function[], but I cannot figure out how (Sorry for my ignorance, I am new in Mathematica).
Cheers!
