SAS/IML software provides a powerful and flexible matrix programming language in a dynamic, interactive environment for programmers, statisticians and researchers. You can use the SAS System for data manipulation and statistical analysis, then employ the SAS/IML matrix language for more specialized analyses and exploration.
The 8.2 release of SAS/IML introduces tools for wavelet analysis to the SAS System. Wavelets are a versatile tool for understanding and analyzing data, with important applications in nonparametric modeling, pattern recognition, feature identification, data compression, and image analysis. Wavelets provide a description of your data that localizes information at a range of scales and positions. New subroutines for computing, inverting and displaying wavelet transforms are now available.
