convert/unit_free - convert to unit-free form
Calling Sequence
convert(u, unit_free, unit)
Parameters
u
-
expression
unit
(optional) name
Description
The convert(u, unit_free) function returns the unit-free component of u. If u is of type unit, then is returned.
The convert(u, unit_free, unit) function returns the unit-free component of u and assigns the unit component of u to unit. If u is of type unit, then is returned. If u is unit-free, then is assigned to unit.
The term unit-free describes a scalar quantity with no (multiplicative) unit attached to it. Conversion to unit-free does not apply directly to any non-scalar Maple object or data structure, which may still have units embedded within it.
Examples
The conversion to unit_free state does not recurse into, or map over, non-scalar objects. Examples illustrating such mapping or effective unit-stripping recursion are shown below.
If a non-scalar object contains a mix of units then it may be desirable to combine the units or convert to a single system, so as to get correct scaling.
