Promote-class function

The Promote class.

This class represents the promotion of a scalar expression into a vector/matrix. class

Arguments

• expr: An Expression or numeric constant.
• promoted_dim: The desired dimensions.
• object: A Promote object.
• values: A list containing the value to promote.
• 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(Promote): Promotes the value to the new dimensions.
• is_symmetric(Promote): Is the expression symmetric?
• dim_from_args(Promote): Returns the (row, col) dimensions of the expression.
• is_atom_log_log_convex(Promote): Is the atom log-log convex?
• is_atom_log_log_concave(Promote): Is the atom log-log concave?
• get_data(Promote): Returns information needed to reconstruct the expression besides the args.
• graph_implementation(Promote): The graph implementation of the atom.

Slots

• expr: An Expression or numeric constant.
• promoted_dim: The desired dimensions.
