SetUnits Command

Changes physical type of vector-name to physical-type . Physical type may be any of the following:

'unknown'	'?'
'Voltage'	'V'
'Current'	'A'
'Time'	'Secs'
'Frequency'	'Hertz'
'Resistance'	'Ohm'
'Conductance'	'Sie'
'Capacitance'	'F'
'Inductance'	'H'
'Energy'	'J'
'Power'	'W'
'Charge'	'C'
'Flux'	'Vs'
'Volt???MATH???^2???MATH???'	'V???MATH???^2???MATH???'
'Volt???MATH???^2???MATH???/Hz'	'V???MATH???^2???MATH???/Hz'
'Volt/rtHz'	'V/rtHz'
'Amp???MATH???^2???MATH???'	'A???MATH???^2???MATH???'
'Amp???MATH???^2???MATH???/Hz'	'A???MATH???^2???MATH???/Hz'
'Amp/rtHz'	'A/rtHz'
" (means dimensionless - see notes)

Note that this command uses non-standard abbreviations for seconds (Secs), Hertz (Hertz) and Siemens (Sie). These are compatible with the Units function. The UnitsNew function returns the standard abbreviations 's', 'Hz' and 'S' respectively.

The physical type of a vector is the name of the physical quantity it represents e.g. Voltage, Current, Time etc. This is used by graph plotting routines to set appropriate units for axes. To set a vector as dimensionless, use the following syntax:

SetUnits vector {"}

SetUnits <vector-name> <units>
