Abstract
An interpolation procedure using the rational spline approximation is presented . The rational spline contains an adjustable tension parameter for each pair of uccessive knots such that in the limit of zero tension, the spline reduces to a conventional cubic spline and in the limit of infinite tension the spline reduces to a straight line . The procedure for adjusting the tension parameters is completely automated such that by adjusting the tension it is possible to achieve the quot;bestquot; fit (in a least-squares sense) of the data .A detailed derivation of the algorithm is presented along with its procedural implementation.the method is successfully implemented on a computer and tested for two cases . Recommendations are made for further extension and application of this method.
