Hello,

What is the proper use of the pivoting version of lu_factorize?  In 
particular, are there requirements on the initial contents of the 
pivoting vector 'pm'?  I get an assertion thrown unless I initialize 
each element of the vector to be equal to its index.  I had thought that 
I only needed to make sure it had the right size.  An example would be 
very helpful.

This occurs in Boost 1.32.0 and also in the head version in the Boost 
repository.
