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.
