The Exp class.
This class represents the elementwise natural exponential e^x.

x |
An Expression object. |
object |
An Exp object. |
values |
A list of numeric values for the arguments |
idx |
An index into the atom. |
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
