144-2013: Getting Started with the SAS/IML® Language
Paper 144-2013 Getting Started with the SAS/IML LanguageRick Wicklin, SAS Institute you need a statistic that is not computed by any SAS procedure? Reach for the SAS/IML Language !Many statistics are naturally expressed in terms of matrices and vectors. For these, you need a paper introduces the SAS/IML Language to SAS programmers who are familiar with elementary linearalgebra. The focus is on statements that create and manipulate matrices, read and write data sets, andcontrol the program flow. The paper demonstrates how to write user-defined functions, interact with otherSAS procedures, and recognize efficient programming SAS/IML Language is a high-level matrix programming Language that enables you to use naturalmathematical syntax to write custom algorithms and to compute statistics that are not built into any SASprocedure. The initials IML stand for interactive matrix Language . This paper is based on Chapters 2 4 ofWicklin(2010b).

For small matrices, you can manually type the elements. Use spaces to separate columns; use commas to separate rows.
