A wrapper around nleqslv from the nleqslv package
to solve a non linear system of equations.
findRoots(beta.init, eq.func, d.eq.func = NULL, arg.list, ...)An initial guess for the zero.
A function of two variables for which the zero are sought. Its first
argument beta should be a vector over which the zeros are sought and
the second argument arg.list a list of additional arguments.
A function to return the Jacobian of eq.func taking the same
arguments as eq.func. Supplying this function can speed up
calculations. Default is NULL.
The second argument to eq.func and d.eq.func
A list of additional arguments to be passed to nleqslv
The value is a list containing the following arguments:
The zero(s) of the function eq.func.
The optimization object returned from nleqslv.
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.
