Hi All, I am looking for help in partition a list based on columns. For ex, given a list {{3,1},{2,4}}, I want to sort it and then partition it along columns. So for the given example, I want the answer to be, {{1,3},{2,4}}. Right now If I try, Partition[Sort[Flatten[{{3,1},{2,4}}]]],2], I get {{1,2},{3,4}}. Looking at doc for Partition[], it doesn't seem to support aligning rows on columns. I can do it in a For[] loop, but that seems un- mathematica like, is there a good functional way to do this?? ------------ What would be a good way to line up elements in a list in a diagonal fashion, for ex: from Range[9] want to create the follwing matrix: 1 2 4 3 5 7 6 8 9 Thanks in advance!
