Units[AddSystem] - add or modify a system of units
Calling Sequence
AddSystem(system, opts, units)
Parameters
system
-

opts
(optional) equation of the form true or false; specify options for the system
units
symbol; any number of existing units to be associated with the given system.
Description
The AddSystem(unit_name, opts, units) function adds or redefines a system of units in the current session.
To add or redefine a system of units in all future Maple sessions, add the AddSystem command to your Maple initialization file. For more information, see Create Maple Initialization File.
A system cannot have two units with the same dimension.
The opts argument can contain the following equation.
truefalse
If this option is set to true, an exception will be generated if two units with the same dimension are associated with the system. Otherwise, the last unit with the given dimension will be associated with the system. The default value of 'check' is false.
Units to be associated with the given system are listed.
Examples
Error, (in Units:-AddSystem) the system already contains a unit with dimension `time`
