Arguments

• expr: An Expression or numeric matrix.
• object: An UpperTri 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(UpperTri): Vectorize the upper triagonal entries.
• validate_args(UpperTri): Check the argument is a square matrix.
