st: Re: Mata question

[Kit Baum <baum@bc.edu>]

I don't understand the question. The J(nrow, ncol, value) function in  
both Stata and Mata creates a rectangular array which can be any  
shape (including row or column vector and, in Mata, an object with 0  
rows and/or columns). It does not have anything to do with symmetry.
