in thread perlxs and gcc error

Yes, that would be what i want to do. However if i change "double &in_matrix" to "double ** in_matrix", this happens:
$ make
/usr/bin/perl -I/usr/lib/perl5/5.6.1/i386-linux -I/usr/lib/perl5/5.6.1
+ /usr/lib/perl5/5.6.1/ExtUtils/xsubpp  -typemap /usr/lib/perl5/5.6.1/
+ExtUtils/typemap test_c.xs > test_c.xsc && mv test_c.xsc test_c.c
Error: 'double **' not in typemap in test_c.xs, line 8
make: *** [test_c.c] Error 1

    The typemap is a mapping from C types to Perl internal types. There are many predefined types, but as you can imagine, it would be impossible to list them all. It looks like double ** isn't in the typemap (which doesn't quite surprise me). So, you have to either extend the typemap, or use the appropriate Perl internal types.

    I don't know how to extend the typemap. My knowledge of XS is extremely limited.
