Thanks. Unfortunately I'm stuck with boost-1.30.2 and it doesn't have
lu_* in it. I have lu.hpp but I get compile errors with bcc-5.6.4 in
lu.hpp hence why I wondered if there was a way to do it using ublas, but

Don't know what MTL is. I have a look. Thanks

X is typically ~500 by 5 (don't know if that counts as big or not, last
time I did matrix work, we only used 3x3 and 4x4 so to me it seems
pretty huge, but we were doing stuff by hand).
I'll have to have a look around for another library if there is no way
to do it with ublas without using lu_*.
Thanks for your help
