Arguments

...

Expression objects or matrices. All arguments must have the same number of columns.

object

A VStack 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(VStack): Vertically concatenate the values using rbind.

• validate_args(VStack): Check all arguments have the same width.

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

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

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

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