The NormNuc class.
The nuclear norm, i.e. sum of the singular values of a matrix.

A |
An Expression or numeric matrix. |
object |
A NormNuc object. |
values |
A list of numeric values for the arguments |
idx |
An index into the atom. |
to_numeric: The nuclear norm (i.e., the sum of the singular values) of A.
allow_complex: Does the atom handle complex numbers?
dim_from_args: The atom is a scalar.
sign_from_args: The atom is positive.
is_atom_convex: The atom is convex.
is_atom_concave: The atom is not concave.
is_incr: The atom is not monotonic in any argument.
is_decr: The atom is not monotonic in any argument.
.grad: Gives the (sub/super)gradient of the atom w.r.t. each variable
