skipped tests

[Doug Stewart]

I am using ubuntu and tip from hg.

In fntests.log I see

>>>>> processing /home/doug/octave_dev/compiling/octave/src/DLD-FUNCTIONS/lu.cc

  ***** testif HAVE_QRUPDATE_LUU

 [L,U,P] = lu(A);

 [L,U] = luupdate(L,U,P*u,v);

 assert(norm(vec(tril(L)-L),Inf) == 0)

 assert(norm(vec(triu(U)-U),Inf) == 0)

 assert(norm(vec(P'*L*U - A - u*v.'),Inf) < norm(A)*1e1*eps)

 

----- skipped test

  ***** testif HAVE_QRUPDATE_LUU

 [L,U,P] = lu(Ac);

 [L,U] = luupdate(L,U,P*uc,vc);

 assert(norm(vec(tril(L)-L),Inf) == 0)

etc.

In lu.cc   at the bottom we have

%!testif HAVE_QRUPDATE_LUU

%! [L,U,P] = lu(A);

%! [L,U] = luupdate(L,U,P*u,v);

%! assert(norm(vec(tril(L)-L),Inf) == 0)

%! assert(norm(vec(triu(U)-U),Inf) == 0)

%! assert(norm(vec(P'*L*U - A - u*v.'),Inf) < norm(A)*1e1*eps)

%! 

%!testif HAVE_QRUPDATE_LUU

%! [L,U,P] = lu(Ac);

%! [L,U] = luupdate(L,U,P*uc,vc);

etc

What I don't see is where HAVE_QRUPDATE_LUU is initilased to be true or false.

I am assuming it is FALSE and therefore skipping the tests.
