The Promote class.

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

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.
