DiagMat-class: The DiagMat class.

In CVXR: Disciplined Convex Optimization

The DiagMat class.

Description

This class represents the extraction of the diagonal from a square matrix.

Usage

DiagMat(expr)

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

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

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

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

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

Arguments

expr	An Expression representing the matrix whose diagonal we are interested in.
object	A DiagMat 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(DiagMat): Extract the diagonal from a square matrix constant.

• dim_from_args(DiagMat): The size of the atom.

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

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

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

Slots

expr

An Expression representing the matrix whose diagonal we are interested in.
