Hi Allan,
It seems like what you're after is more-or-less the same as converting from
sparse matrix storage, so the mata code here should do the trick:
http://www.stata.com/statalist/archive/2009-04/msg00142.html
You just need to get your variables into a mata matrix to start with and you
should be away:
mata : st_view(x=.,.,("var2","var1","var3"))
NB: Note the inverted order of var1 and var2. This is because the code for
-sparse()- assumes that the first variable provides the row index, and the
second variable provides the column index.
HTH,
Glenn.

Hi, All,
I have three variables (var1, var2, var3). I would like to create a
matrix where the values of var1 are the columns (ascending), the
values of var2 are the rows (also ascending), and the values of var3
are the elements in the matrix. I know there must be a user defined
procedure out there to do this, but I haven't been able to find it.
Thanks,
Allan
