Abstract
A curve interpolation scheme based on piecewise rational quadratic spline is discussed. To preserve the shape of the data, the constraints are made on the free parameters r i , in the description of rational quadratic interpolant. We examine the positivity and/or monotonicity preserving of this rational quadratic interpolant to a given data set. The method easy to used and require less computational steps. The degree of smoothness attained is C 1 Some numerical results will be presented.
