SAS/IML is the matrix programming language component to SAS (similar to R).

SAS/IML is the matrix language component of SAS software. It interfaces with the base SAS programming environment, allowing you to smoothly transition from matrix operations to dataset operations, and to use SAS' full suite of statistical tools while enjoying the power of a fully featured matrix language.

SAS/IML also allows an interface into R, to allow users to take advantage of the power of SAS while maintaining the flexibility of using R packages as well.
