# S4 method for Exp
is_atom_log_log_convex(object)
# S4 method for Exp
is_atom_log_log_concave(object)
# S4 method for Exp
is_incr(object, idx)
# S4 method for Exp
is_decr(object, idx)
# S4 method for Exp
.grad(object, values)

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: The matrix with each element exponentiated.

• sign_from_args: The atom is positive.

• is_atom_convex: The atom is convex.

• is_atom_concave: The atom is not concave.

• is_atom_log_log_convex: Is the atom log-log convex?

• is_atom_log_log_concave: Is the atom log-log concave?

• is_incr: The atom is weakly increasing.

• is_decr: The atom is not weakly decreasing.

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

Slots

x

An '>Expression object.
