Like this? test = RandomInteger[{0, 10}, 10] {5, 9, 9, 2, 0, 4, 10, 4, 5, 4} NestList[Rest[# - #[[1]]] &, test, 9] {{5, 9, 9, 2, 0, 4, 10, 4, 5, 4}, {4, 4, -3, -5, -1, 5, -1, 0, -1}, {0, -7, -9, -5, 1, -5, -4, -5}, {-7, -9, -5, 1, -5, -4, -5}, {-2, 2, 8, 2, 3, 2}, {4, 10, 4, 5, 4}, {6, 0, 1, 0}, {-6, -5, -6}, {1, 0}, {-1}} Bobby On Sat, 28 Mar 2009 05:40:09 -0500, bahadir <bahadirgurbuz54 at hotmail.com> wrote: > i have a list with n element.i want to pick out an element from the > list, and to deduct the element from all the other residual elements. > This process is the first step. i must apply all elements of the list, > invariably.
