Spline Functions on the Circle: Cardinal L-Splines Revisited
Canadian Journal of Mathematics, 1980Although the literature on splines has grown vastly during the last decade [11], the study of polynomial splines on the circle seems to have suffered neglect. The first to study the subject in depth seem to be Ahlberg, Nilson and Walsh [1]. Almost at the same time I. J.

Cardinal Interpolation and Generalized Exponential Euler Splines
Canadian Journal of Mathematics, 1976Let denote the class of cardinal splines S(x) of degree n (n ≧ 1) having their knots at the integer points of the real axis. We assume that the knots are simple so that . Recently Schoenberg [3] has studied cardinal splines such that S(x) interpolates the exponential function tx at the integers ...

Lebesgue Constants for Cardinal -Spline Interpolation
Canadian Journal of Mathematics, 1977Recently the theory of cardinal polynomial spline interpolation was extended to cardinals -splines [3]. Letbe a polynomial with only real zeros. Denote the set of zeros by . If is the associated differential operator, the null-space

The cardinal L-splines are linear combinations of certain exponential polynomials between successive integers. Here we consider a subset $S_n^r (T)$ of this class which generalizes the concept of perfect splines and determine the element with the least t-norm for some nonzero real t.

Let F(x) be a function from ℝ to ℂ and let $$S_m \left( x \right)\, = \,\sum\limits_{ - \infty }^\infty {F\left( \nu \right)L_m \left( {x - \nu } \right)}$$ (1) be the spline function of degree 2m−1, with knots at the integers, that interpolates F(x) at all the integers.

A Family of Generalized Cardinal Polishing Splines
IEEE Transactions on Image ProcessingSpline functions have received widespread attention in the fields of image sampling and reconstruction. To enhance the performance of splines in reconstruction and reduce the computational burden of solving large linear equations, we propose a family of generalized cardinal polishing splines (GCP-splines) and provide a system of linear equations to ...
