Arguments

x

An '>Expression object.

object

A '>Square 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)

• validate_args: Verification of arguments happens during initialization.

• to_numeric: The elementwise square of the input value.

• get_data: A list containing the output of pow_high.

• 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_quadratic: Is x affine?

• graph_implementation: The graph implementation of the atom.

Slots

x

An '>Expression object.
