Promote-class: The Promote class.

In CVXR: Disciplined Convex Optimization

The Promote class.

Description

This class represents the promotion of a scalar expression into a vector/matrix.

Usage

Promote(expr, promoted_dim)

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

## S4 method for signature 'Promote'
is_symmetric(object)

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

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

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

## S4 method for signature 'Promote'
get_data(object)

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

Arguments

expr	An Expression or numeric constant.
promoted_dim	The desired dimensions.
object	A Promote object.
values	A list containing the value to promote.
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(Promote): Promotes the value to the new dimensions.

• is_symmetric(Promote): Is the expression symmetric?

• dim_from_args(Promote): Returns the (row, col) dimensions of the expression.

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

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

• get_data(Promote): Returns information needed to reconstruct the expression besides the args.

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

Slots

expr

An Expression or numeric constant.

promoted_dim

The desired dimensions.
