Numerical Hessian
Description
Numerical Hessian
Usage
hessian0(f, x, args)
Arguments
f
Function to differentiate.
x
Vector at which to evaluate the Hessian.
args
List of additional arguments from the function richardson_args.
Value
A list with the form of a hessian_result described in section "Hessian"
of the package vignette.
Examples
f = function(x) { sum(x^2) }
x0 = seq(1, 10, length.out = 5)
args = richardson_args()
