[ublas] find2 required by Matrix?

Does the Matrix concept require a find2 member function?  My locally 
defined matrix class does not work with lu_factorize (with pivots) 
unless I provide that function.  Alternatively, do some of the ublas 
algorithms have stronger requirements on the matrix classes than defined 
by the Matrix concept?
