Let us consdier the system of fractional order delay differential equation
D^[alpha} x(t)= a*x(t) ( 1- x(t)/k ) - (b* x(t)* y(t-tau) ) / ( 1+c* x(t) );
D^[alpha} y(t)= ( b* x(t)* y(t-tau) ) / ( 1+c* x(t) )-d y(t);
tau=0.5; a=1; k=2; b=0.5; c=1.5; [x(t), y(t)]=[2,1] for all t in [-0.5, 0].
How to plot the above system?

I set a=1, k=2, b=0.5, c=1.5, d=1.2, and alpha=0.95, then get the following plot. Is it right? ##### 댓글 수: 5표시숨기기 이전 댓글 수: 4

The alpha value is the order of your equations. About the matlab code you can read the paper: A PREDICTOR-CORRECTOR SCHEME FOR SOLVING NONLINEAR DELAY DIFFERENTIAL EQUATIONS OF FRACTIONAL ORDER. SACHIN BHALEKAR, VARSHA DAFTARDAR-GEJJI.

I have read the article ''A PREDICTOR-CORRECTOR SCHEME FOR SOLVING NONLINEAR DELAY DIFFERENTIAL EQUATIONS OF FRACTIONAL ORDER''. I have some confusion on ploting the system of equation. Please send me the matlab code for the same. Otherwise give your mail id sir. I will explian my dobuts detailly via mail. My mail id is '' []@gmail.com''
