NPL's GUM Supplement 2 Software
-------------------------------

This file describes the files that constitute Release 1 of NPL's 
GUM Supplement 2 Software (also known as NPL's NPLUnc_102 Software).

The software was developed at the National Physical Laboratory, UK, 
to support the use of the Guide to the expression of uncertainty in 
measurement (GUM) and the second supporting document to the GUM, 
GUM Supplement 2, concerned with multivariate models, i.e., models 
having any number of output quantities. The software enables users 
to apply the approaches to uncertainty evaluation described in these 
documents to two of the example problems considered in GUM Supplement 
2. The software is intended to allow users to reproduce the results 
presented in tables and figures contained within GUM Supplement 2. 
It is also intended to help users learn about the methods for 
uncertainty evaluation described in the GUM and GUM Supplement 2 
by enabling them to experiment with (a) different information about 
the input quantities in the models defining the example problems, 
and (b) different values for the parameters controlling the 
application of those methods, e.g., the number of trials in an 
application of a Monte Carlo method.

The software, developed in the MATLAB programming language, is 
provided in the form of application files generated using MATLAB 
Version 7.11.0 (R2010b).
