MATLAB: Intersections between 2 graphs

intersectionMATLABpolargraphs

r=@(o)(2+sin(3.*o))./(sqrt(1+exp(cos(o))));

o=linspace(-pi,pi);

[x,y]=pol2cart(o,r(o));

plot(x,y)

hold on

[a,b]=cirkel(0,0,1); %Draws a circle with [0,0] as center and 1 radius

plot(a,b,'r')

How do I find the intersection of these two figures?

I get this graph if I run the program Circle and a clover.png

Try this software on fex

imshow(your_image);
hold on
t=0:0.1:2*pi;
%x_o and y_o = center of circle
x = x_o + radio*sin(t);
y = y_o + radio*cos(t);
plot(x,y,'r');
hold off
