Arguments

object

An '>AffAtom object.

idx

An index into the atom.

Methods (by generic)

  • sign_from_args: The sign of the atom.

  • is_atom_convex: The atom is convex.

  • is_atom_concave: The atom is concave.

  • is_incr: The atom is weakly increasing in every argument.

  • is_decr: The atom is not weakly decreasing in any argument.

  • is_quadratic: Is every argument quadratic?

  • is_pwl: Is every argument piecewise linear?
