How do I determine eigenvalues in matlab?

Assume I have the model of a complex continuous system which consists of several differential equations as follows:

f = 1/(ura235 + 2.43*plu239 + 2.679*plu241) 
d/dt ura236 = (.016*ura235 - 0.0012*uran236)*f 
d/dt uran235 = -0.106*f*ura235
.
.
.

How do I determine the eigenvalues of such series of equations in Matlab without having to manually form the Jacobian matrix?

Any help would be greatly appreciated...

I think you can do this without forming the Jacobian. If this is a nonlinear set of equations, then simply plug in at a given value of the solution and extract eigenvalues. I believe eig(A) will do this for you.
