Homework Help: Mathematica,Pattern matching and ReplaceRepeated.

  1. Apr 21, 2012 #1
    1. The problem statement, all variables and given/known data

    Given a list of integers, use pattern matching and //.to create a rule that generates an ordered list of integers that are larger than the previous numbers in the list, eg given {3,5,2,0,6,1,8,4,9}, you should get {3,5,6,8,9}

    2. Relevant equations

    3. The attempt at a solution

    Well calling our arbitrary list L, I tried
    rules={___,x_,y_,___}/;x>y :→{___,x,___}; then
    L //. rules . From this I just get {5}?
    I haven't used pattern matching alot, so what else am I meant to do?
