MATLAB: Drawing a star with n points

drawing shapes star sketching graphshomeworkstarturtle

Hi guys I have this question to do but I have no clue for any of it.

First write a function file star.m with first line function turtle=star(turtle,npoints,R,r) which uses turtle to draw a star centred at the turtle’s current location. Inputs: • turtle: an initialized turtle to draw the star with; • npoints: the number of points the star; • R: distance from the centre of the star to the points; • r: distance from the centre to the inward corners between the points. Output turtle: turtle used for drawing in its new state. One point of the star should point in the initial direction of the turtle.

Thanks help would be appreciated.

Did you search the forum: http://www.mathworks.com/matlabcentral/answers/32786-six-pointed-star

Attached are my only two star demos. You're welcome to adapt them.

Use the FAQ to draw a circle, then exponentiate:

http://matlab.wikia.com/wiki/FAQ#How_do_I_create_a_circle.3F

xCenter = 12;
yCenter = 10;
theta = 0 : 0.01 : 2*pi;
radius = 5;
x = radius * cos(theta) + xCenter;
y = radius * sin(theta) + yCenter;
xe = exp(x);
ye = exp(y);
loglog(xe, ye, 'LineWidth', 2);
axis square;
grid on;
hold on;
% Draw second circle
radius = 3;
x = radius * cos(theta) + xCenter;
y = radius * sin(theta) + yCenter;
xe = exp(x);
ye = exp(y);
loglog(xe, ye, 'LineWidth', 2);

MATLAB: Plotting distance values with lines

I’m not certain what you intend by ‘display’, but if you want the distances as numbers, perhaps near each point, I suggest you experiment with the text function.
