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.

• dim_from_args(UpperTri): The dimensions of the atom.

• is_atom_log_log_convex(UpperTri): Is the atom log-log convex?

• is_atom_log_log_concave(UpperTri): Is the atom log-log concave?

• graph_implementation(UpperTri): The graph implementation of the atom.

Slots

expr

An Expression or numeric matrix.
