NPLUnc_101 supports the use of the Guide to the Expression of Uncertainty in Measurement (GUM) and GUM Supplement 1, concerned with the use of a Monte Carlo method for uncertainty evaluation.

NPLUnc_102 supports GUM Supplement 2, concerned with extending measurement models to any number of output quantities.

The software is available in two different forms, either stand-alone Window programs or as open source code developed in MATLAB.
