Arguments

• x: An Expression object.
• object: An Abs object.
• values: A list of arguments to the atom.
• idx: An index into the atom.

Methods (by generic)

• to_numeric(Abs): The elementwise absolute value of the input.
• allow_complex(Abs): Does the atom handle complex numbers?
• sign_from_args(Abs): The atom is positive.
• is_atom_convex(Abs): The atom is convex.
• is_atom_concave(Abs): The atom is not concave.
• is_incr(Abs): A logical value indicating whether the atom is weakly increasing.
• is_decr(Abs): A logical value indicating whether the atom is weakly decreasing.
• is_pwl(Abs): Is x piecewise linear?

Slots

• x: An Expression object.
