Trace-class: The Trace class.

In CVXR: Disciplined Convex Optimization

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

expr

An Expression representing a matrix.
