My code:
clc;
close all
clear all;
f=input('please enter the dim=')
t=linspace(0,2*pi,7);
for Z=[-f/2:1:f/2]
for j=-f/2:1.732:f/2
ao=((Z)*1.5)+1*cos(t);
bo=(j)+1*sin(t);
plot(ao,bo);
plot(Z*1.5,(j),'ro')
hold on
end
for k=-f/2:1.732:f/2
al=((-Z)*1.5)+1*cos(t);
bl=(k)+1*sin(t);
plot(al,bl);
plot(-Z*1.5,k,'ro')
hold on
end
end
the result when I enter dim=10 is hexa generated but overlapping each other and I want it matching for planning.

This code generate fixed area of hexa and i need to make it changable

ah=0+1*cos(t);
bh=i+1*sin(t);
plot(ah,bh);
plot(0,i,'ro');
hold on
end
for j=1.732:1.732:10

Note: this graph will have the appearance that the hexagons are overlapped. They are not overlapped: it is an illusion that is partly generated because you wanted the hexagons lined up on a grid instead of being staggered like they are in a honeycomb.

thank you but i still need it not overlapped the following code is generate hexa with fixed area :
clc;
close all
clear all;
t=linspace(0,2*pi,7);
ahx=0+1*cos(t);
bhx=0+1*sin(t);
plot(ahx,bhx);
for i=-0.866:1.732:10
ah=0+1*cos(t);
bh=i+1*sin(t);
plot(ah,bh);
plot(0,i,'ro');
hold on
end
for j=1.732:1.732:10
ar=1.5+1*cos(t);
br=j+1*sin(t);
plot(ar,br);
plot(1.5,j,'ro')
hold on
end
for k=1.732:1.732:10
al=-1.5+1*cos(t);
bl=k+1*sin(t);
plot(al,bl);
plot(-1.5,k,'ro')
hold on
end
grid on
SO,i need to make that area changable not fixed
thanks again for your answer and hope you help me with this

The code I gave does NOT overlap anything. It might _look_ like it does, but that is an illusion because all the lines are the same color.
Here is a minor modification to the routine to change the coloring so that you can see more clearly that there is no overlap.
t = linspace(0,2*pi,7);
f = input('please enter the (even) dim=');
clf
hold on
xlim([-f/2,f/2]);
ylim([-f/2,f/2]);
axis square
L = f/2 - 1;
Zp = -L : 2 : L;
jp = Zp * sqrt(3) / 2;
colord = 'bgkcmy';
colidx = 0;
for Z = Zp
for j = jp
colidx = mod(colidx,length(colord)) + 1;
ao = Z + cos(t);
bo = j + sin(t);
plot(ao, bo, colord(colidx));
plot(Z, j, 'ro')
end
end

Your duplicate questions have been merged in to your original question, and the duplicate questions have been deleted.
Before anyone can assist you, you need to give a clear description of what you are trying to achieve. For example,
"I am attempting to project a Hexadecachoronic Honeycomb to two dimensions, from the 4-dimensional viewpoint [v1,v2,v3,v4], looking towards [w1,w2,w3,w4], and [...]"
