Calling Sequence
Parameters
Description
Examples
combine(expr, 'units', opts)
expr
-
algebraic expression
opts
equation(s) of the form option=value where option is one of 'mode' or 'system'; specify options for combining units
The combine/units function combines, if possible, expressions involving units into a unit-free expression multiplied by a Unit object.
The conversion can be implemented as combine(expr, 'units', 'mode'='natural').
The opts argument can contain one or more of the following equations that set options for how units are interpreted and combined.
'mode'=standard or natural or simple
The mode standard indicates that Maple uses routines and operations from the Units[Standard] environment, whereas the mode natural indicates routines and operations from the Units[Natural] environment and simple indicates routines and operations from the Units[Simple] environment.
The default mode is set by the UseMode command, which is called if you load Units[Standard], Units[Natural], or Units[Simple]. If the command hasn't been called, the default mode is standard.
'system'=symbol
By default, any result is converted to the default system of units, which by default is SI. By specifying a different system of units, the result is converted, if possible, to that system.
Note: Prior to Maple 2015, units were displayed surrounded by double brackets.
