Units (updated)

Converts between units with checks for unit consistency.

Description

This is a simple update of the Units.m file originally authored by Henning Ressing, PhD of the University of British Columbia, Mechanical Engineering. This update checks for unit consistency. This file now supports parsecs as a unit of length conversion. Please contact me FIRST if this file does not work to your standards.

>> Z=units(1,'in','Yotta')
Inconsistent unit - please check units and try again!
??? One or more output arguments not assigned during call to 'units'.

>> Z=units(1,'Yotta','in')
Z =

It should be noted that units(updated) only supports unit conversion within groups of items (as listed within the help function of this m-file). As "in" is a unit of length, and "Yotta" is unitless, units will not convert them. The proper function call to do this would be:

>>Z=units(1,'Yotta','1')

[Mark M]

This needs to be fixed for temperature conversions for the second unit, line 980 to 987, change "c" to "x".
