 Keith reported on the mailing list (sorry don't have latest numpy
 installed currently to test myself but Keith is usually reliable ...) that
 the functions nanmin, nanmax, nanargmin, nanargmax, nansum return an array
 when given a matrix subclass, as opposed to virtually all other numpy

 (due to first line being y=array(a))
