  Description   : implementation of class module Matrix
                  
  History       :
    matvec.nw
     980630 fh: first noweb version of generic_matrix
     980925 fh: inserted constructors with 1/2/3 field parameters from statmatrix
     981007 fh: reorganization of refinements
    matvec.matrix.nw:
     980831 fh: first statmatrix implementation
     980925 fh: moved constructors with 1/2/3 field parameters to matrix.nw
     990107 fh: refinements reorganization
    matvec.init-diag.nw:
     990107 fh: moved constructors from matvec.diagmat.nw
