Dear all,
Can anyone advise me what's the "proper" way to reset (remove) row / column equations from a matrix?
I've been using using the method: 
.matrix roweq A = :
and this worked with all the versions (or at least 8-10) just fine, but unfortunately doesn't with the version 11. In V11 the command doesn't return any error but leaves the matrix unchanged. It seems that for version 11 the alternative method:
.matrix roweq A = "" does the trick but as you'd guess, this syntax doesn't work with the previous versions.
Does anyone know if there is a way to remove row equations in a way that would work in Stata versions 9-11? or the only way is to have an if statement checking for the version?
Any insight will be much appreciated.
