Hello,

I have a dataset with three columns: the first two are the i and j
coordinates of a potential matrix, and the third is the data that
would go into the (i,j)th spot. Is there a way (in Stata or Mata) to
create a matrix directly from these three variables? I've tried using
-mkmat- to create a column vector which gets sent to Mata, where it's
looped through into a new matrix. However, as a column vector the data
exceeds the maximum matrix size in my version of Stata (though as a
square matrix it would not).

Sincerely,
Sam Bailey
