Arguments

• 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.

Methods (by generic)

• to_numeric(DiagMat): Extract the diagonal from a square matrix constant.
• dim_from_args(DiagMat): The size of the atom.
• is_atom_log_log_convex(DiagMat): Is the atom log-log convex?
• is_atom_log_log_concave(DiagMat): Is the atom log-log concave?
• graph_implementation(DiagMat): The graph implementation of the atom.

Slots

• expr: An Expression representing the matrix whose diagonal we are interested in.
