You may follow the below approach.....You have to draw circles and call the function rose...
clc; clear all ;R = 1 ; % radius of circle
th = linspace(0,2*pi) ; % angle
% make circle
x = R*cos(th) ; y = R*sin(th) ;plot(x,y,'r') ;hold on% Draw roses
rose(0.01, 2, 1)axis equalHow to plot left semi circle:
The key is to compute theta values between pi/2 and 3*pi/2.
x=5; y=10;r=3;theta = linspace(pi/2, 3*pi/2, 100); % <-- left half of circlexCirc = r * cos(theta) + x;yCirc = r * sin(theta) + y;cla()plot(xCirc, yCirc)axis equalgrid onxline(x)yline(y)
