# MATLAB: Plotting of for loop

for loop plot

Halo
Please can anyone tell me why my for loop is not plotting for all the points on one graph but only the last value of the for loop.
a=0.171296;b=0.856479;c=0.25;d=0.85285;k1=d/a;k2=d/c;k3=((a^2)-(b^2)+(c^2)+(d^2))/(2*a*c);k4=d/b;k5=((c^2)-(d^2)-(a^2)-(b^2))/(2*a*b);for theta2=1:1:360;    A=cosd(theta2)-k1+k3-k2*cosd(theta2);B=-2*sind(theta2);C=k1-k2*cosd(theta2)+k3-cosd(theta2);D=cosd(theta2)-k1+k5+k4*cosd(theta2);E=-2*sind(theta2);F=k1+k4*cosd(theta2)+k5-cosd(theta2);theta3=(2*atand((-E-(sqrt((E.^2)-(4*D.*F))^0.5)))./(2*D));   theta4=(2*atand((-B-(sqrt((B.^2)-(4*A.*C))^0.5)))./(2*A));  omega2=0.5;omega3=((a*omega2)/b)*((sind(theta4-theta2))/(sind(theta3-theta4)));omega4=((a*omega2)/c)*((sind(theta2-theta3))/(sind(theta4-theta3)));plot (theta2,omega3,'b-')grid on;hold on;legend('omega 3');xlabel('theta 2');ylabel('omega 3');title ('Velocity of links 3 & 4');plot (theta2,omega4,'r-')grid on;legend('omega 4');xlabel('theta 2');ylabel('omega 4');title ('Velocity of links 3 & 4');hold off;end
Thank you
