Source: R/affine.R

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

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
