You can do this in Mata.
. mata :
: exp((0,1\2,3))
1 2
+-----------------------------+
1 | 1 2.718281828 |
2 | 7.389056099 20.08553692 |
+-----------------------------+
You can also pass a Stata matrix into Mata to do this and pull back the result.
. matrix foo = (0,1\2,3)
. mata : st_matrix("foobar", exp(st_matrix("foo")))
. mat li foobar
foobar[2,2]
c1 c2
r1 1 2.7182818
r2 7.3890561 20.085537
