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.
