You can get the indexes using the -rownumb()- and -colnumb()-
functions, and feed these to the -el()- function, like in the
example below
*------- begin example -----------
sysuse auto, clear
reg price mpg foreign
matrix v = e(V)
matrix list v
tempname foo
scalar `foo' = el(v, ///
rownumb(v,"_cons"), ///
colnumb(v,"_cons"))
di `foo'
*------- end example --------------
(For more on how to use examples I sent to the Statalist, see

Hope this helps,
Maarten
