How to plot a regular hexagon using MATLAB?

This is what I tried. All I get is a square. I thought the number of x and y gives the figure.

x1=1;y1=-1;x2=-1;y2=1;x3=1;y3=1;x4=-1;y4=-1;x5=1;y5=1;x6=-1;y6=1;
plot(x1,y1,'o',x2,y2,'*',x3,y3,'h',x4,y4,'d',x5,y5,'k',x6,y6,'g')
axis([-2 2 -2 2])

What am I doing wrong? Please help!

Thanks for your time.

Points 3 and 5 are the same, and points 2 and 6 are the same, so they'll plot at exactly the same place.

This is how I did it:

theta= 0:pi/3:2*pi
r= ones(1,7)
polar(theta,r)

Try this:

theta = 0:60:360;
x = cosd(theta);
y = sind(theta);
plot(x, y, 'b-', 'LineWidth', 3);
axis square;
grid on;
% Enlarge figure to full screen.
set(gcf, 'units','normalized','outerposition',[0 0 1 1]);

% Plot markers if you want.
plot(x(1),y(1),'o',x(2),y(2),'*',x(3),y(3),'h',...
  x(4),y(4),'d',x(5),y(5),'s',x(6),y(6),'x', ...
  'MarkerFaceColor',[.49 .1 .63], 'MarkerSize', 30)

Thanks a lot, Image Analyst. Is that linspace? The way you used theta. I got exacly what I was aiming for.

Thanks for your time.

[Image Analyst]

It wasn't linspace(), but you could use linspace() if you wanted to, to get x.

a=4; b=4;c=4; x=[a c*0.5 -b*0.5 -a -c*0.5 b*0.5 a]; y=[0 c*0.866 b*0.866 0 -c*0.866 -b*0.866 0];

plot(x,y); axis([-6 6 -6 6])

% use this function

   function hexagon(cote,x0,y0)
   %cote= side size;,(x0,y0) exagon center coordinates;
   x=cote*[-1 -0.5 0.5 1 0.5 -0.5 -1]+x0
   y=cote*sqrt(3)*[0 -0.5 -0.5 0 0.5 0.5 0]+y0
   plot(x,y,'r','Linewidth',4);grid;
   axis([ x0-cote x0+cote y0-cote y0+cote]);

%example

    hexagon(10,5,8)

Thank you Azzi Abdelmalek, I finally understood how functon works.

Thanks for your time.

do i need to include any tools for running this function? its not running by only copy paste !

how to name each vertex of hexagon?

[Image Analyst]

What do you mean by "name"? Like you want to use text() to place a string next to each vertex?
