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$^2$' 'V$^2$'
'Volt$^2$/Hz' 'V$^2$/Hz'
'Volt/rtHz' 'V/rtHz'
'Amp$^2$' 'A$^2$'
'Amp$^2$/Hz' 'A$^2$/Hz'
'Amp/rtHz' 'A/rtHz'
" (means dimensionless - see notes)
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 {"}
