Use matlab ode45 to integrate set of diff. equations

Use of ode45 to complete this...however, I am not sure how to go about it.

1.) integrate set of diff. equations with given initial conditions and constants and plot concentration profiles of all 5 dependent variables
2.) plot phase plot of s1 vs s2. What does the phase plot demonstrate? ...I don't know?
3.) perform a stability analysis examining the eigenvalues (matlab eig function) of Jacobian matrix around the steady state.

The solution is made using the matlab routine ode45.
Its arguments are
--- reference to the function odefun(t,y) which calculates the vector of derivatives dy/dt = yp(t,y)
--- the points in time at which you want to know the values of vector y
--- the initial values of vector y
The results of the integration are plotted in figure 101
