Adding lists individually, not sum


    Jan 19 2013 | 4:26 pm
    Ex, I have 4 lists:
    1 0 0 0 1 0 0 0
    1 0 1 0 1 0 1 0
    1 0 0 0 0 0 0 0
    1 1 1 1 1 1 1 1
    i want to add the numbers "by column" so for this example it would be:
    4 1 2 1 3 1 2 1
    right now my solution involves splitting each list and adding them separately which involves a lot of objects (iter, count indexing, route, thresh, zl sum). Is there a more elegant way to do this?

      perfect! since getting into list processing i've learned a bunch of new objects. haven't used vexpr before. thanks for the help!
