algorithm 600, collected algorithms from acm.

algorithm appeared in acm-trans. math. software, vol.9, no. 2, jun., 1983, p. 258-259.

TSpline5 computes the coefficients of a quintic natural quintic spli s(x) with knots x(i) interpolating there to given function values: s(x(i)) = y(i) for i = 1,2, ..., n. in each interval (x(i),x(i+1)) the spline function s(xx) is a polynomial of fifth degree: s(xx) = ((((f(i)*p+e(i))*p+d(i))*p+c(i))*p+b(i))*p+y(i) (*) = ((((-f(i)*q+e(i+1))*q-d(i+1))*q+c(i+1))*q-b(i+1))*q+y(i+1) where p = xx - x(i) and q = x(i+1) - xx. (note the first subscript in the second expression.) the different polynomials are pieced together so that s(x) and its derivatives up to s"" are continuous.

input:

n number of data points, (at least three, i.e. n > 2) x(1:n) the strictly increasing or decreasing sequence of knots. the spacing must be such that the fifth power of x(i+1) - x(i) can be formed without overflow or underflow of exponents. y(1:n) the prescribed function values at the knots.

output:

b,c,d,e,f the computed spline coefficients as in (*). (1:n) specifically b(i) = s'(x(i)), c(i) = s"(x(i))/2, d(i) = s"'(x(i))/6, e(i) = s""(x(i))/24, f(i) = s""'(x(i))/120. f(n) is neither used nor altered. the five arrays b,c,d,e,f must always be distinct.

option:

it is possible to specify values for the first and second derivatives of the spline function at arbitrarily many knots. this is done by relaxing the requirement that the sequence of knots be strictly increasing or decreasing. specifically:

if x(j) = x(j+1) then s(x(j)) = y(j) and s'(x(j)) = y(j+1), if x(j) = x(j+1) = x(j+2) then in addition s"(x(j)) = y(j+2).

note that s""(x) is discontinuous at a double knot and, in addition, s"'(x) is discontinuous at a triple knot. the subroutine assigns y(i) to y(i+1) in these cases and also to y(i+2) at a triple knot. the representation (*) remains valid in each open interval (x(i),x(i+1)). at a double knot, x(j) = x(j+1), the output coefficients have the following values: y(j) = s(x(j)) = y(j+1) b(j) = s'(x(j)) = b(j+1) c(j) = s"(x(j))/2 = c(j+1) d(j) = s"'(x(j))/6 = d(j+1) e(j) = s""(x(j)-0)/24 e(j+1) = s""(x(j)+0)/24 f(j) = s""'(x(j)-0)/120 f(j+1) = s""'(x(j)+0)/120 at a triple knot, x(j) = x(j+1) = x(j+2), the output coefficients have the following values: y(j) = s(x(j)) = y(j+1) = y(j+2) b(j) = s'(x(j)) = b(j+1) = b(j+2) c(j) = s"(x(j))/2 = c(j+1) = c(j+2) d(j) = s"'((x(j)-0)/6 d(j+1) = 0 d(j+2) = s"'(x(j)+0)/6 e(j) = s""(x(j)-0)/24 e(j+1) = 0 e(j+2) = s""(x(j)+0)/24 f(j) = s""'(x(j)-0)/120 f(j+1) = 0 f(j+2) = s""'(x(j)+0)/120

Test method for TSpline5.

n number of data points. m 2*m-1 is order of spline. m = 3 always for quintic spline. nn,nm1,mm, mm1,i,k, j,jj temporary integer variables. z,p temporary double precision variables. x[n] the sequence of knots. y[n] the prescribed function values at the knots. a[200][6] two dimensional array whose columns are the computed spline coefficients diff[5] maximum values of differences of values and derivatives to right and left of knots. com[5] maximum values of coefficients.

test of TSpline5 with nonequidistant knots and equidistant knots follows.
