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