%      The following  M-files are available for work with pp functions
%      (but see also  splist.m  for M-files for spline work):
%
%       pp = ppmak(breaks,coefs[,d])   makes up a pp function
%
%       [break,coefs,k,l,d] = ppbrk(pp)   takes it apart
%
%       [values=] fnplt(pp)   plots on a fine grid
%
%       v=fnval(pp,x)    evaluates (calling on  ppual.m )
%       dpp=fnder(pp[,m])    differentiates
%       ipp=fnint(pp)   integrates
%
%       fncmb(pp1,sc1[,pp2[,sc2]])    forms weighted sum of two like pp's
%
%       pj=pppce(pp,j)   pulls out the j-th polynomial piece
%
%       pc=ppcut(pp,[a b])  pulls out the part relevant for the interval
%                           [a .. b] 
%
%       (values = ) fnplt(pp[,symbol])  plots pp between its extreme breaks.
