A list of additional arguments to be passed to |
findRoots
calculates zeros fo the function eq.func
and is the default equation solving function in drgee
.
It is supplied as a separate function in order to allow users
to use other equation solvers by writing their own wrapper
with the same interface as findRoots
.
The value is a list containing the following arguments:
roots |
The zero(s) of the function |
optim.object |
The optimization object returned from |
