Just copy to a regular vector first: 

sysuse auto
gen gpm = 1 / mpg
regress gpm  weight length displacement

. mat li e(b)

e(b)[1,4]
          weight        length  displacement         _cons
y1     .00001174     .00006458     5.517e-06     .00152916

. mat b = e(b)

. mat b1 = b[1, "weight".. "length"]

. mat li b1

b1[1,2]
       weight     length
y1  .00001174  .00006458

I would like to access to a subvector of a vector like e(b) or e(V). 
Stata allows to have et sub-element as _b[varname]. Is it possible to have _b[varlist] ?
