The Trace class.
This class represents the sum of the diagonal entries in a matrix.

expr |
An Expression representing a matrix. |
object |
A Trace object. |
values |
A list of arguments to the atom. |
arg_objs |
A list of linear expressions for each argument. |
dim |
A vector representing the dimensions of the resulting expression. |
data |
A list of additional data required by the atom. |
to_numeric: Sum the diagonal entries.
validate_args: Check the argument is a square matrix.
dim_from_args: The atom is a scalar.
is_atom_log_log_convex: Is the atom log-log convex?
is_atom_log_log_concave: Is the atom log-log concave?
graph_implementation: The graph implementation of the atom.
