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.
