  "Description": "Solves ordinary and delay differential equations, where\nthe objective function is written in either R or C.  Suitable\nonly for non-stiff equations, the solver uses a\n'Dormand-Prince' method that allows interpolation of the\nsolution at any point.  This approach is as described by\nHairer, Norsett and Wanner (1993) <ISBN:3540604529>.  Support\nis also included for iterating difference equations.",
