Use Join rather than Append pcin = 2; pcex = 3; coin = Table[{10 RandomReal[], 10 RandomReal[]}, {pcin}]; coex = Table[{3 RandomReal[], 3 RandomReal[]}, {pcex}]; cobo = Join[coin, coex]; Dimensions[cobo] {5, 2} Bob Hanlon On Mon, Apr 14, 2014 at 5:28 AM, Ste[hen Gray <stevebg at roadrunner.com>wrote: > pcin = 2; > pcex = 3; (*pcin and pcex can have various small values *) > > coin = Table[{10 RandomReal[], 10 RandomReal[]}, {pcin}] > coex = Table[{3 RandomReal[], 3 RandomReal[]}, {pcex}] > cobo = Append[coin, coex] > > > gives, typically, > > {{0.288346, 3.57763}, {1.7335, 8.69666}} > {{0.179831, 1.35324}, {0.927483, 0.931586}, {1.76338, 2.45073}} > {{0.288346, 3.57763}, {1.7335, > 8.69666}, {{0.179831, 1.35324}, {0.927483, 0.931586}, {1.76338, > 2.45073}}} > > What I want is a series of x,y coordinates with no extra nesting: > > {{0.288346, 3.57763}, {1.7335, > 8.69666}, {0.179831, 1.35324}, {0.927483, 0.931586}, {1.76338, > 2.45073}} > > I'm embarrassed to admit that I can't find how to do this. > > Please email me.
