How to code for the following coordinates?

Let N denotes no. of antennas placed along an axis.Now if I have total 7 antennas i.e., N=7 and I place each antenna 0.5 apart on each axis, then if I want to place 3 antennas on x-axis, 3 antennas on y-axis and no antenna on z-axis, i.e., their co-ordinates are as below:

0 0 0

1.5000 0 0

1.0000 0 0

0.5000 0 0

0 1.5000 0

0 1.0000 0

0 0.5000 0

How will I code for this?

I did it myself. So if any body needs it, here it is:

clear all
clc
N=11;%9;%7;
d=0.5;
r=zeros(N,3);
x=[0 d:d:(N-1)/2*d zeros(1,(N-1)/2)]';%x=[0 d 2*d 3*d 0 0 0]';%x=[0 0.5 1 1.5 0 0 0]';
y=[zeros(1,(N+1)/2) d:d:(N-1)/2*d]';%y=[0 0   0  0  d 2*d 3*d]';%y=[0 0   0  0  0.5 1 1.5]';
z=zeros(1,N)';%z=[0 0 0 0 0 0 0]';
r=[x y z]

Hi Sadiq Akbar,

From my understanding of your question, you want to place a total of 3 antennas on x-axis, 3 antennas on y-axis and no antenna on z-axis.Im assuming that the 7th antenna is at origin.The following is a code snippet which generates the coordinates of the 7 antennas,

m=zeros(7,3);
d=0.5;
for i=2:4
    m(i,1)=m(i-1,1)+d;
end
for i=5:7
    m(i,2)=m(i-1,2)+d;
end

Thank you very much dear SAI SRUJAN for your help. But I have already done it and shared it above.
