The Log1p class.

Source: R/elementwise.R

This class represents the elementwise operation \(\log(1 + x)\).

Arguments

x

An Expression or numeric constant.

object

A Log1p object.

values

A list of numeric values for the arguments

Methods (by generic)

  • to_numeric(Log1p): The elementwise natural logarithm of one plus the input value.

  • sign_from_args(Log1p): The sign of the atom.

  • .grad(Log1p): Gives the (sub/super)gradient of the atom w.r.t. each variable

  • .domain(Log1p): Returns constraints describng the domain of the node

Slots

x

An Expression or numeric constant.
