Re: st: set value to zero in a Matrix

What I meant was that if there is an -esttab- (SSC) way of doing what
you want I don't know what it is. (Fine program; it's just that I
never use it.)
You have defined -a- as a Stata matrix.
Mata knows nothing about it. Use the -st_matrix()- function. You still
have to affect e-class results.
Please direct any further questions on this problem to other members
of the list.
