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.

A Powerful Language for a Wide Range of Applications

You can apply SAS/IML software to problems ranging from simple matrix manipulations to estimation techniques and linear programming to nonlinear optimization. An extensive set of mathematical and matrix operators make the possibilities endless. Graphics routines provide access to data visualization tools from within the SAS/IML environment.

SAS/IML software is a complete programming language. You can construct programs using control structures such as conditional and iterative statements, and access a wide range of built-in subroutines to make your programming even more efficient. You can transfer data to and from SAS data sets and external files with data management commands. SAS/IML software automatically performs the bookkeeping of memory management and matrix sizing. The type, dimension, and size of variables can change with each use.
