i need to plot 2 lines (e.g. Ax+By+C), 2 circles (e.g.(x-h)^2 + (y-k) ^2 = r^2), and 3 points (e.g. (x1,y1), (x2,y2) & (x3,y3)) all in one plot, for instructional purposes. how do i plot a circle centered at (h,k) with radius r?
% plot CM = jet(N); % See the help for COLORMAP to see other choices. figure hold on for ck = 1:N xcircle = xc(ck) + R(ck)*cos(th) ; ycircle = yc(ck) + R(ck)*sin(th) ; % a=rand(1,3); % color triplet value , so below th...
glOrtho(0, 321, 31, 0, -z,z);//画球时,Z轴范围要大于球的半径radius,z>radius画球时,这样才可见 glLoadIdentity(); glTranslatef(circle1_x,y, 0);//Z轴向里为正,平移到足以放下整个球,否则球的部分可能在屏幕外,看不见,屏幕上显示的是Z最小值的地方。 glColor3f(157 / 255.0 ...

Plot Circle Copy Code Copy Command Plot a circle centered at the point (4,3) with a radius equal to 2. Use axis equal to use equal data units along each coordinate direction. Get r = 2; xc = 4; yc = 3; theta = linspace(0,2*pi); x = r*cos(theta) + xc; y = r*sin(...
I am trying to plot 50 random points on a circle with a radius of 500 then store the x, y coordinates of the points in a matrix and calculate each point's distance from the centre of the circle (0,0), any reference I could use or how I can achieve this?
