Convert three array into one matrix.

I have two array 1xn (A1....An), 1xm(B1...Bm) and value Z. I want to create one matrix nxm rows and 3 columns as follow:

A1 B1 Z,
A1 B2 Z,
...
A1 Bm Z,
A2 B1 Z,
...
An B1 Z,
...
An Bm Z

I do not know how to create this. Could you please help me to solve this problem. Thanks for your help.

Use meshgrid:

>> A = 1:3;
>> B = 4:7;
>> Z = 8;
>> [Am,Bm,Zm] = meshgrid(A,B,Z);
>> [Am(:),Bm(:),Zm(:)]
ans =
   1   4   8
   1   5   8
   1   6   8
   1   7   8
   2   4   8
   2   5   8
   2   6   8
   2   7   8
   3   4   8
   3   5   8
   3   6   8
   3   7   8

n = 3;
m = 5;
A = rand(1,n)
B = rand(1,m)
Z = 10;
res = [reshape(repmat(A,m,1),n*m,1) repmat(B',n,1) Z*ones(n*m,1)]
