Input Parameters

ts - the TS context obtained from TSCreate()
splitname - name of this split
r - vector to hold the residual (or NULL to have it created internally)
rhsfunc - the RHS function evaluation routine
ctx - user-defined context for private data for the split function evaluation routine (may be NULL)

t - time at step/stage being solved
u - state vector
f - function vector
ctx - [optional] user-defined context for matrix evaluation routine (may be NULL)
