Description

• 

The function GetSystem(system) returns all units in a system of units.

• 

For an existing system system, the call AddSystem(system, GetSystem(system)) recreates an equivalent system. The calling sequence AddSystem(system, check, GetSystem(system), new_unit) redefines the system by including new_unit and ensuring that new_unit does not have the same dimension as any of the existing units in system.
