take this code:
clc
x=input('enter the value of x: ');
y=input('enter the value of y: ');
r=input('enter the value of R: ');
n=input('enter the value of N: ');
d=sqrt(3*n)*r

axis([0 x 0 y ])

c=r;
v=30:60:390;
cv=r*cosd(v);
sv=r*sind(v);

for y=0:2:y
for w=0:2:x
line(w*sqrt(3)/2*c+cv,y*1.5*c+sv,'tag','h');
end
end

for m=1:2:y
for k=1:2:x
line(k*sqrt(3)/2*c+cv,m*1.5*c+sv,'tag','h');
end
end
