What is the role of plist in CVODES?
The argument plist to CVodeSetSensParams is used to specify the problem parameters with respect to which solution sensitivities are to be computed. plist is used only if the sensitivity right-hand sides are evaluated using the internal difference-quotient approximation function. In that case, plist should be declared as an array of Ns integers and should contain the indeces in the array of problem parameters p with respect to which sensitivities are desired.
