Arguments

x

An Expression object.

object

An Exp object.

values

A list of numeric values for the arguments

idx

An index into the atom.

Methods (by generic)

  • to_numeric(Exp): The matrix with each element exponentiated.

  • sign_from_args(Exp): The atom is positive.

  • is_atom_convex(Exp): The atom is convex.

  • is_atom_concave(Exp): The atom is not concave.

  • is_atom_log_log_convex(Exp): Is the atom log-log convex?

  • is_atom_log_log_concave(Exp): Is the atom log-log concave?

  • is_incr(Exp): The atom is weakly increasing.

  • is_decr(Exp): The atom is not weakly decreasing.

  • .grad(Exp): Gives the (sub/super)gradient of the atom w.r.t. each variable

Slots

x

An Expression object.
