Notice that I am not using the coefficient of the *variable* consump,
but of the *variable* wagepriv in the *equation* consump. (this
corresponded most what you intended to do, as far as I understood your
question: the first variable in the first equation)
How you build a matrix is discussed in -help matrix define-. You can
stack a row underneath an existing matrix using \, as is shown in the
example below:
*---------------- begin example -----------------
webuse klein
reg3 (consump wagepriv wagegovt) ///
(wagepriv consump govt capital1) if year < 0
matrix foo = [consump]_b[wagepriv], ///
[consump]_b[wagepriv]/[consump]_se[wagepriv]
matrix list foo
reg3 (consump wagepriv wagegovt) ///
(wagepriv consump govt capital1) if year >= 0
matrix foo = foo \ ///
[consump]_b[wagepriv], ///
[consump]_b[wagepriv]/[consump]_se[wagepriv]
matrix list foo
*----------------- end example ------------------
(For more on how to use examples I sent to the Statalist, see

Hope this helps,
