Trace-class {CVXR}

The Trace class.

Description

This class represents the sum of the diagonal entries in a matrix.

Usage

Trace(expr)

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

## S4 method for signature 'Trace'
validate_args(object)

## S4 method for signature 'Trace'
dim_from_args(object)

## S4 method for signature 'Trace'
is_atom_log_log_convex(object)

## S4 method for signature 'Trace'
is_atom_log_log_concave(object)

## S4 method for signature 'Trace'
graph_implementation(object, arg_objs, dim, data = NA_real_)

Arguments

expr

An Expression representing a matrix.

object

A Trace object.

values

A list of arguments to the atom.

arg_objs

A list of linear expressions for each argument.

dim

A vector representing the dimensions of the resulting expression.

data

A list of additional data required by the atom.

Methods (by generic)

• to_numeric(Trace): Sum the diagonal entries.

• validate_args(Trace): Check the argument is a square matrix.

• dim_from_args(Trace): The atom is a scalar.

• is_atom_log_log_convex(Trace): Is the atom log-log convex?

• is_atom_log_log_concave(Trace): Is the atom log-log concave?

• graph_implementation(Trace): The graph implementation of the atom.

Slots
