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.
