Arguments

e1, e2

The Expression objects or numeric constants to add.

x, object

An AddExpression object.

values

A list of arguments to the atom.

args

An optional list of arguments to reconstruct the atom. Default is to use current args of the atom.

id_objects

Currently unused.

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)

• dim_from_args(AddExpression): The dimensions of the expression.

• name(AddExpression): The string form of the expression.

• to_numeric(AddExpression): Sum all the values.

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

• is_atom_log_log_concave(AddExpression): Is the atom log-log convex?

• is_symmetric(AddExpression): Is the atom symmetric?

• is_hermitian(AddExpression): Is the atom hermitian?

• copy(AddExpression): Returns a shallow copy of the AddExpression atom

• graph_implementation(AddExpression): The graph implementation of the expression.

Slots

arg_groups

A list of Expressions and numeric data.frame, matrix, or vector objects.
