| hessian {dfdr} | R Documentation |
Compute the Hessian-function of a function.
Description
Creates a function that computes the second-order derivatives of a function with respect to each pair of parameters and return a vector of these.
Usage
hessian(f, use_names = FALSE, ...)
Arguments
f |
A function |
use_names |
Should the gradient add variable names to the output of the function? |
... |
The variable names for which gradients should be calculated |
Value
A function that computes the gradient of f at any point.
Examples
f <- function(x, y) x**2 + y**2
h <- hessian(f, FALSE, x, y)
h(0, 0)
