(tau(i), c(1,i), i=1,...,n) = abscissae and ordinates of the data points. tau is assumed to be strictly increasing. ibcbeg, ibcend = boundary condition indicators, and c(2,1), c(2,n) = boundary condition information. specifically, ibcbeg = 0 means no boundary condition at tau(1) is given. in this case, the not-a-knot condition is used, i.e. the jump in the third derivative across tau(2) is forced to zero, thus the first and the second cubic polynomial pieces are made to coincide.) ibcbeg = 1 means that the slope at tau(1) is made to equal c(2,1), supplied by input. ibcbeg = 2 means that the second derivative at tau(1) is made to equal c(2,1), supplied by input. ibcend = 0, 1, or 2 has analogous meaning concerning the boundary condition at tau(n), with the additional infor- mation taken from c(2,n). *********************** output ************************** c(j,i), j=1,...,4; i=1,...,l (= n-1) = the polynomial coefficients of the cubic interpolating spline with interior knots (or joints) tau(2), ..., tau(n-1). precisely, in the interval (tau(i), tau(i+1)), the spline f is given by f(x) = c(1,i)+h*(c(2,i)+h*(c(3,i)+h*c(4,i)/3.)/2.) where h = x - tau(i). the function program ppvalu may be used to evaluate f or its derivatives from tau,c, l = n-1, and k=4.
