In cvxgrp/CVXR: Disciplined Convex Optimization

The Log1p class.

Description

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

Usage

Log1p(x)

## S4 method for signature 'Log1p'
to_numeric(object, values)

## S4 method for signature 'Log1p'
sign_from_args(object)

## S4 method for signature 'Log1p'
.grad(object, values)

## S4 method for signature 'Log1p'
.domain(object)

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.
