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 Expression s and numeric data.frame, matrix, or vector objects.
