Arguments

x

An '>Expression object.

object

An '>Abs object.

values

A list of arguments to the atom.

idx

An index into the atom.

arg_objs

A list of linear expressions for each argument.

size

A vector with two elements representing the size of the resulting expression.

data

A list of additional data required by the atom.

Methods (by generic)

  • to_numeric: The elementwise absolute value of the input.

  • sign_from_args: The atom is positive.

  • is_atom_convex: The atom is convex.

  • is_atom_concave: The atom is not concave.

  • is_incr: A logical value indicating whether the atom is weakly increasing.

  • is_decr: A logical value indicating whether the atom is weakly decreasing.

  • is_pwl: Is x piecewise linear?

  • graph_implementation: The graph implementation of the atom.

Slots

x

An '>Expression object.
