Arguments

• lh_exp: An Expression or R numeric data.
• rh_exp: An Expression or R numeric data.
• object: A Multiply 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(Multiply): Multiplies the values elementwise.
• dim_from_args(Multiply): The sum of the argument dimensions - 1.
• is_atom_log_log_convex(Multiply): Is the atom log-log convex?
• is_atom_log_log_concave(Multiply): Is the atom log-log concave?
• is_psd(Multiply): Is the expression a positive semidefinite matrix?
• is_nsd(Multiply): Is the expression a negative semidefinite matrix?
• graph_implementation(Multiply): The graph implementation of the expression.
