I want to know the way to call the animation from classdef.
I defined the animatedline in classdef, and I called the animation to other code from the classdef.
But it did not showed the animation.
close all;
Length1 = 1.0;
Length2 = 1.0;
Mass1 = 1.0;
Mass2 = 1.0;
Ts = 0.01;
Theta_Initial1 = 0;
Theta_Initial2 = 0;
AngularVelocity_Initial1 = 0;
AngularVelocity_Initial2 = 0;
Pendulum2 = classDoublePendulum(Length1,Length2,Mass1,Mass2,Theta_Initial1,Theta_Initial2,AngularVelocity_Initial1,AngularVelocity_Initial2,Ts);
Trq = [10; 10];
for i=1:100
Pendulum2.Dstep(Trq); % call classdef but animation did not work.
end
Please someone help me , teach me the way.
classdef classDoublePendulum < handle
