When using simple lu_factorize and lu_substitute, I get lots of compiler 
warnings. I do get the right results, but I'm bugged about the warnings. 
Is ublas not part of the boost code base ? is there something wrong with 
my usage? how do i stop the warnings without suppressing individual 
warnings in my Visual Studio project?

Warnings are as below:

TYPE 1
