Theory n The chaotic actions of the individual shifts to the ordered actions of a collective system n n n θ = The individual phase of the fireflies ω = The initial velocity of the θ Θ = The phase of the stimulus Ω = The velocity of the Θ φ = Θ – θ : phase difference A = Ability of Synchronization
How to evaluate the equation? ■ ODE 45 function의 사용 V 0 = [th 0; Lt 0; ph 0; ohm; self; depend] – 초기값의 입력 [t, V] = (‘equation’, 1: time, V 0(: , n)); - 미분방정식 실행 ■ equation. m function d. V = equation(t, V) w = V(4) -(0. 001*(V(5))*rand) ; A = (0. 0025*V(6)); d. V = zeros(6, 1); d. V(1) = w + A * sin(V(2) - V(1)); d. V(2) = V(4); d. V(3) = V(4)- w - (A * sin(V(3)));
Image Constructing n C=zeros(20, 3); 를 지정해주어 가로세 로 20인 RGB image matrix를 만든다. n 입력된 number 만큼의 pixel을 random으 로 지정해준다.
Image Constructing 반딧불이가 있는 각 element들에 대해 Point=1일 때는 Yellow Point=0일 때는 grey 를 씌워준다. 매 time iteration 마다 image(c); 와 drawnow; 를 통해 image를 덮어 쉬워 동 적인 image를 구현한다.
