paper AIAA-2006-7049 in the Proceedings of the 11th AIAA/ISSMO Multidisciplinary Analysis and
Optimization Conference, Portsmouth, VA, Sept. 6-8, 2006.
Surfpack is a general-purpose software library of multidimensional function
approximation methods for applications such as data visualization, data mining, sensitivity
analysis, uncertainty quantification, and numerical optimization. Surfpack is primarily
intended for use on sparse, irregularly-spaced, n-dimensional data sets where classical
function approximation methods are not applicable. Surfpack is under development at
Sandia National Laboratories, with a public release of Surfpack version 1.0 in August 2006.
This paper provides an overview of Surfpack’s function approximation methods along with
some of its software design attributes. In addition, this paper provides some simple examples
to illustrate the utility of Surfpack for data trend analysis, data visualization, and
