In nabla: Exact Derivatives via Automatic Differentiation
dual_variable R Documentation
Create a dual variable (derivative seed = 1)
Description
Convenience constructor for the independent variable when computing
derivatives. Sets deriv = 1 so that the output's derivative slot
contains df/dx.
Usage
dual_variable(x)
Arguments
x
A numeric value.
Value
A dual with value = x and deriv = 1.
Examples
x <- dual_variable(2)
deriv(x^2)
