Mata matters: Using views onto the data

Abstract

development, and principal architect of Mata Mata is Stata's matrix language. In the Mata Matters column, we show how Mata can be used interactively to solve problems and as a programming language to add new features to Stata. In this issue's column, we explore view matrices, matrices that are views of the underlying Stata dataset rather than copies of it. © 2005 StataCorp LP.
