Arguments

• x: An Expression object.
• object: An Exp object.
• values: A list of numeric values for the arguments
• idx: An index into the atom.

Methods (by generic)

• to_numeric(Exp): The matrix with each element exponentiated.
• sign_from_args(Exp): The atom is positive.
• is_atom_convex(Exp): The atom is convex.
• is_atom_concave(Exp): The atom is not concave.
• is_atom_log_log_convex(Exp): Is the atom log-log convex?
• is_atom_log_log_concave(Exp): Is the atom log-log concave?
• is_incr(Exp): The atom is weakly increasing.
• is_decr(Exp): The atom is not weakly decreasing.
• .grad(Exp): Gives the (sub/super)gradient of the atom w.r.t. each variable

Slots

• x: An Expression object.
