Contrary to another poster's comment, st_view() will not help here. st_view allow you to access Stata's variables, not matrices or "vectors" (note that Stata does not have a vector data type; all "vectors" are matrices with a unit subscript on one dimension. Mata has true vectors, rowvectors and colvectors).

st_local
st_global
st_numscalar
st_matrix

allow you to do the same with Stata's macros, scalars and matrices. They all have one- and two-argument forms. The one-argument form allows you to access the Stata object; the two-argument form allows you to update the contents (or indeed create) the Stata object. See

help m4_stata

for a complete list of the functions of this nature.

If one is working with program or do file in Stata and wishes to move
to Mata within the program to use a Mata function for a matrix or
vector defined in the Stata program, is this possible?
