I believe this will work. The {1,1} uses overhang at the end, and the 0 is the character to use. P = {"1", "1", "1", "1", "0", "1", "0", "1"} Reverse[Partition[p, 3, 3, {1, 1}, 0]] {{"0", "1", 0}, {"1", "0", "1"}, {"1", "1", "1"}} -- Dana DeLouis Windows XP $VersionNumber -> 4.2 = = = = = = = = = = = = = = = = = "flip" <flip_alpha at safebunch.com> wrote in message news:amem4s$41p$1 at smc.vnet.net... > b = 2; r = 4; > n = "10101111" > p = Reverse[Characters[n]] > {"1", "1", "1", "1", "0", "1", "0", "1"} > z = Reverse[Partition[p, r]] > {{"0", "1", "0", "1"}, {"1", "1", "1", "1"}} (* this is okay *) > b = 2; r = 3; > z = Reverse[Partition[p, r]] > {{"1", "0", "1"}, {"1", "1", "1"}} (* this is wrong, want output to be > {{0,1,0},{1,0,1},{1,1,1}}*) > > What I want is a function that takes a string as input, parses each > character, partitions that to whatever length I want and Prepends zeros to > the input as needed to create an appropriate length array. > > What is the correct syntax for Partition (or is there a better way?). > > Thanks, Flip > > Remove _alpha to email.
