Thanks for this advice. You are right, linearalgebra.mac loads load-linearalgebra-lisp-
files.lisp, so that everything is included.

I was puzzled by the output of lu_factor, which does not correspond to the example in the 
A look into the source code of lu-factor clarifies that lu_factor returns a list of three entries
	     `((mlist) ,m ,perm ,(mring-name fld)))))))
where the last is the name of the ring. So it's just that there is an update of the 
documentation needed.

I already put the functions from eval_string, numericalio and stringproc to the list of 
autoloaded functions this morning. Please let me know if I should also add linearalgebra 
before April 4 or if I should wait.
