The populations of Canis lupus (wolves) and Rangifer tarandus (reindeer)

in the environment can be described by the system of differential equations

(

X′(t) = X(t)(a − bY (t))

Y ′(t) = Y (t)(cX(t) − d),

(1)

where X(t) is the population of Rangifer tarandus and Y (t) is the population

of Canis lupus. The constants are a = 8, b = .25, c = .02 and

d = 10 and the initial populations are X(0) = 600 and Y (0) = 60. Using

the MATLAB code ode45 solve (1) for 0 <= T<= 2 and plot X(t) and Y(t)
