Arguments

expr

An Expression representing the vector to convert.

object

A DiagVec 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(DiagVec): Convert the vector constant into a diagonal matrix.

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

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

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

• is_symmetric(DiagVec): Is the expression symmetric?

• is_hermitian(DiagVec): Is the expression hermitian?

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

Slots
