JacobianODE

JacobianODE:

-------------------------------------------------------------------------------
   This function computes the Jacobian matrix for a right hand-side.
   The central difference approximation good to O(h^2) is used.
   For any function f(x,t) it will compute the f0 and a matrices.

   f(x,t) ‰ f(xOP,tOP) + a(xOP,tOP) x + Š

   funFcn is input as a character string 'xxxxx' and must be of the form
   xdot = xxxxx ( t, x, flag, d )
   which is the same form used in ode113. 

-------------------------------------------------------------------------------
   Form:
   [a, fOP] = JacobianODE( funFcn, tOP, xOP, d )
