The DiagMat class.
This class represents the extraction of the diagonal from a square matrix.

expr |
An Expression representing the matrix whose diagonal we are interested in. |
object |
A DiagMat 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: Extract the diagonal from a square matrix constant.
dim_from_args: The size of the atom.
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.
