Arguments

• arg1: The first Expression in the maximum operation.
• arg2: The second Expression in the maximum operation.
• ...: Additional Expression objects in the maximum operation.
• object: A MaxElemwise object.
• values: A list of numeric values for the arguments
• idx: An index into the atom.

Methods (by generic)

• to_numeric(MaxElemwise): The elementwise maximum.
• sign_from_args(MaxElemwise): The sign of the atom.
• is_atom_convex(MaxElemwise): The atom is convex.
• is_atom_concave(MaxElemwise): The atom is not concave.
• is_atom_log_log_convex(MaxElemwise): Is the atom log-log convex?
• is_atom_log_log_concave(MaxElemwise): Is the atom log-log concave?
• is_incr(MaxElemwise): The atom is weakly increasing.
• is_decr(MaxElemwise): The atom is not weakly decreasing.
• is_pwl(MaxElemwise): Are all the arguments piecewise linear?
• .grad(MaxElemwise): Gives the (sub/super)gradient of the atom w.r.t. each variable

Slots
