%inputs
l1=1;
l2=0.5;

theta1=linspace(0,90,10);
theta2=linspace(0,90,10);

ct=1;

for i=1:length(theta1)
THETA1=theta1(i);
for j=1:length(theta2)
THETA2=theta2(j);
x0=0;
y0=0;

x1=l1*cosd(THETA1);
y1=l1*sind(THETA1);

x2=x1+l2*cosd(THETA2);
y2=y1+l2*sind(THETA2);

(whlile entering this, i made theta1 instead of THETA1, ahich made more time to rectify the error and finally got it.)

%plotting

plot([x0 x1],[y0 y1],[x1 x2],[y1 y2],'LineWidth',3)
axis([-0.1 1.5 0 1.5])
pause(0.03)
m(ct)=getframe(gcf);
ct=ct+1;
end
end

movie(m)
videofile = VideoWriter('forward_kinematics.avi','Uncompressed AVI');
open(videofile)
writeVideo(videofile,m)
close(videofile)

(in this movie option, it still showing some error regarding size, i can't understand why it's showing, but program is running and video saved.)
