- % 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.
