Interesting that you use the word array. Presumably
you mean "matrix"?
Stata's language contains the term matrix. In more general terms, one
might refer to that structure as an array of numbers. I tend to use the
two terms interchangeably, although when programming one must use
"matrix". Speaking of arrays highlights the issue that such structures
are often useful, in Stata programming, for purely housekeeping
details, having nothing to do with linear algebra. Stata "matrices" are
very handy if one wishes to avoid, e.g., storing scalar results without
defining variables to do so.
