The SAS® System provides a powerful and flexible programming language in a dynamic, interactive environment for programmers, statisticians, and researchers. Use the SAS System for data manipulation and general statistical analysis, then employ SAS/IML software’s interactive matrix language for more specific analysis and exploration. The fundamental data element in SAS/IML is the matrix, a two-dimensional (row-by-column) array of numeric or character values. You do not need to declare, dimension, or allocate storage for a data matrix because SAS/IML software does this automatically. You can change the dimension or type of a matrix, reset options, or replace modules at any time. You can open multiple files or access many libraries. Built-in matrix operators, functions, and subroutines can be applied to perform complex tasks such as matrix inversion or eigenvector generation.
