Forward kinematic of 2R robotic arm

Here,

Instead of using Imagemagik apk, I have used an onine GIF maker for converting it to animation. Reason behind not using Imagemagik is that its not working properly in my system. So, I used the alternate one as suggested on dashboard.

Please let me know if there is any mistake. This is my youtube link- https://youtu.be/vQqjr-C4b34

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);

plot([x0 x1],[y0 y1],'linewidth',3,'color','g',[x1 x2],[y1 y2],'linewidth',3,'color','r')

file_text=sprintf("fkd%d.png",ct)
saveas(gca,file_text);
ct=ct+1;
end
