In AWK
For 3 individual vectors of the form:
-2.772 -9.341 -2.857
-5.140 -6.597 -1.823
-2.730 -5.615 1.159
I would like to write a script that parses line by line to (i) normalise, (ii) divide by the norm for *each* vector.

char chr_nm_cd;

using SUN C++ I have a problem when I do a push_back on a vector. The linker gives me a undefined symbol error on __cxa_end_catch.
Any ideas, is there a library to include?
Thanks
