Hello,
Thanks for your remarks. I couldn't realize that I pass the pointers
to the AlterVector function. How should I take a lead on that in the
future? I should be reading the header files I presume.

Absolutely, but this shouldn't solve the problem of accessing
gsl_vector v2 from inside AlterVector, *without* passing it through
the function arguments. I did the following:
-- main.c:
gsl_vector *v2;
main(void) {
...
v2 = gsl_vector_alloc(n);
...
}
and sec.c unaltered, and it worked.
Thanks,
-- G.
