Hi Is there an easy way of finding the maximum y-value of a list of x-y pairs? For example: pairs = {{0, 0.175}, {1, 0.54}, {2, 0.27}, {3, 0.47}, {4, 0.325}, {5, 0.527}, {6, 0.22}, {7, 0.742}, {8, 0.109}, {9, 0.3314}, {10, 0.1481}} Max[pairs] gives 10 which isnt what I want. At the moment I am doing this: maxy = 0; Do[ currentx = pairs[[count]][[1]]; currenty = pairs[[count]][[2]]; If[currenty > maxy, maxy = currenty; x = currentx; ]; , {count, 1, Length[pairs]} ] Print[{x, maxy}] Which gives the maximum y value along with with its x-value but I suspect that there is a much more elegant way. Any help would be appreciated. Thanks, Mike
