;;; This file contains manipulations of simple double-float arrays 
;;; and should be called by the spesialized matrix methods. 
;;; The purpose of this layer is that it can be used by 
;;; many classes such as matrix-base-dge and matrix-base-ddi, etc. 
;;; 
;;; The content of this file must be highly optimized 
;;; and should not depend anything exept Common Lisp itself.
