Trace-class function

The Trace class.

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

## S4 method for signature 'Trace'
graph_implementation(object, arg_objs, dim, data = NA_real_)

Arguments

• 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.

Methods (by generic)

• to_numeric(Trace): Sum the diagonal entries.
• validate_args(Trace): Check the argument is a square matrix.
• dim_from_args(Trace): The atom is a scalar.
• is_atom_log_log_convex(Trace): Is the atom log-log convex?
• is_atom_log_log_concave(Trace): Is the atom log-log concave?
• graph_implementation(Trace): The graph implementation of the atom.

Slots

• expr: An Expression representing a matrix.
