Simple list question
Posted: Apr 14, 2014 5:28 AM

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.
