You've got much more than that going on. -diagt- calls -diagti- which calls many other things, and so on.
Somewhere along that chain, matrices are being cleared.
It's not your problem below, but I did notice that -diagt- overwrites any existing matrix called T. As it destroys such a matrix any way, that's incidental, but using a temporary name would be widely considered better practice.

I´m creating a table using diagt (available from ssc) for different cutoff values of p. However the matrix is lost after calling diagt (version 2.0.5) and the same happens using this example-code:
(stata v10.1)
(ssc install diagt)
sysuse auto.dta
gen ind=price>10000
diagt ind foreign
mat a=(r(sens),r(spec))
mat list a
diagt ind foreign
mat dir
viewsource diagt.ado --no reference as far as I can tell to dropping of matrices...Neither with diagti.
There is a previous post with diagt for bootstrap purposes, but there is no reference to dropping of matrices.
