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
