  <DESCRIPTION>
    <P>
    This function gives for a real or a numerical matrix 
    <VERB> x</VERB> his largest  element <VERB> m</VERB> (but ignoring the
    NANs).</P>
    <P>
    For  <VERB>  x</VERB>,  a   numerical vector  or  matrix, <VERB> m=nanmax(x) </VERB>
    returns in scalar <VERB>  m</VERB> the largest
    element  of <VERB> x</VERB>  (ignoring the NANs). The form 
    <VERB>[m,index] =nanmax(x,orient) </VERB> gives in addition of the
    value of the largest element  of <VERB> x</VERB> (ignoring the
    NANs) in scalar <VERB> m</VERB>, the index  of this element in
    <VERB> x</VERB>, as a 2-vector.</P>
    <P><VERB>m=nanmax(x,'r')  </VERB> gives  in the 1xsize(x,2) matrix
    <VERB> m</VERB> the largest elements  (ignoring the  NANs) of
    each  column    of   <VERB>  x</VERB>.    If   the  form 
    <VERB>[m,index]=nanmax(x,'r') </VERB> is used, the elements of the
    1xsize(x,2) matrix index are the  indexes of the largest
    elements (ignoring the NANs) of each column  of x in the
    corresponding column.</P>
    <P>
    m=nanmax(x,'c') gives  in the size(x,2)x1  matrix m  the
    largest elements (ignoring the NANs)  of each row of  x.
    If   the   form [m,index]=nanmax(x,'c')   is  used,  the
    elements of the size(x,2)x1 matrix index are the indexes
    of the largest elements (ignoring  the NANs) of each row
    of x in the corresponding row.</P>
    <P>
    In   Labostat, NAN values  stand   for missing values  in
    tables.</P>
