It would be helpful if you said more about what you are trying to do
here. If you want four matrices that you can refer to in sequence, this
seems like a good approach. If, say, you want to generate a set of
matrices to pick up the estimation results, maybe something like this is
what you are looking for?
if "`e(cmd)'"=="regress" {
local mats "b V"
}
else if "`e(cmd)'"=="heckman" {
local mats "b V ilog"
}
foreach name of local mats {
tempname mat_`name'
matrix `mat_`name'' = e(`name')
}
How you create the tempnames probably depends on how you want to use
them...
