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?

Can you give me also the mathlab code for the same model please.

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.

HIi, Ravi.
Hope you succeeded in getting MatLab code for fractional delay differential equations. Please let me know the code. I tooo strugling for Matlab code.
