Description

Creates a function that computes the derivative of a function with respect to each parameter and return a vector of these.

Usage

gradient(f, use_names, ...)

Value

A function that computes the gradient of f at any point.

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

Examples

f <- function(x, y) x^2 + y^2
df <- gradient(f, FALSE, x, y)
df(1, 1)
