fn |
A real function of a single variable. |
gr |
A function that computes the gradient of |
x0 |
An initial guess for the value of the root of |
offset |
An inverse tolerance for the root. When a new estimate of the root |
maxiter |
A limit on the number of function evaluations permitted in the attempt to find a root. |
trace |
If TRUE, provided diagnostic output of the process of rootfinding. |
... |
Extra data needed to compute the function |
To be added.
The output is a list consisting of return(list(root=b, froot=NA, rtol=wtol, maxit=maxit)) ## Acceptable approx. is found */
root |
The estimate, b, of the position of the root. |
froot |
The value of the function at this point, f(b). |
rtol |
The width of the interval in which the root exists. |
fcount |
The number of function evaluations used. |
