<DL>
<DD>Creates a new Spline curve by calculating the coefficients of each part
 of the curve, i.e. by resolving the equation system implied by the
 interpolation condition on every interval.
<P>
<DT><B>Parameters:</B><DD><CODE>r</CODE> - an array of float containing the vertical coordinates of the
            nodes to interpolate ; the vertical coordinates start at 0 and
            are equidistant with a step of 1.</DL>

<DD>Resolves the equation system by a Jacobi algorithm. The use of the slower
 Jacobi algorithm instead of Gauss-Seidel is choosen here because Jacobi
 is assured of to be convergent for this particular equation system, as
 the system matrix has a strong diagonal.
