You can define outside the loop a mata function that does the
computations, and than call that function within the loop.
*------------ begin example -----------
mata:
void testtest(real scalar i) {
a = i
printf("i=%g\n", a)
}
end
forvalues i = 1/3 {
mata: testtest(`i')
}
*---------- end example ----------------
Hope this helps,
