DESCRIPTION ^

% -*- texinfo -*-
% @deftypefn {Function File} {@var{pp} = } csape (@var{x}, @var{y}, @var{cond}, @var{valc})
% cubic spline interpolation with various end conditions.
% creates the pp-form of the cubic spline.
%
% the following end conditions as given in @var{cond} are possible. 
% @table @asis
% @item 'complete'    
%    match slopes at first and last point as given in @var{valc}
% @item 'not-a-knot'     
%    third derivatives are continuous at the second and second last point
% @item 'periodic' 
%    match first and second derivative of first and last point
% @item 'second'
%    match second derivative at first and last point as given in @var{valc}
% @item 'variational'
%    set second derivative at first and last point to zero (natural cubic spline)
