plot a hexagon in matlab

To plot a hexagon in MATLAB, you can use the patch function, which allows you to draw polygons with arbitrary shapes and styles. Here's the code to plot a regular hexagon:

main.m
% define vertices of hexagon
r = 1;                      % circumradius
theta = linspace(0, 2*pi, 7);    % angles between vertices
x = r*cos(theta);
y = r*sin(theta);

% plot hexagon using patch function
patch(x, y, 'b', 'EdgeColor', 'k')
axis equal

In the first block of code, we define the vertices of the hexagon. We start with the circumradius r, which is the distance from the center of the hexagon to any of its vertices. We then compute the angles between the vertices using linspace, which generates a sequence of equally spaced numbers between 0 and 2*pi. We use these angles to compute the x and y coordinates of the vertices using the trigonometric functions cos and sin.

In the second block of code, we use the patch function to plot the hexagon. The first two arguments are the x and y coordinates of the vertices. The third argument is the color of the hexagon (blue in this case). The fourth argument specifies the color of the edges of the hexagon (black in this case). Finally, we use axis equal to ensure that the x and y axis have the same scale, so that the hexagon appears as a regular polygon.
