On Interpolation Errors over Quadratic Nodal Triangular Finite Elements
Interpolation techniques are used to estimate function values and their derivatives at those points for which a numerical solution of any equation is not explicitly evaluated. In particular, the shape functions are used to interpolate a solution (within an element) of a partial differential equation obtained by the finite element method. Mesh generation and quality improvement are often driven ...
متن کاملConstrained Interpolation via Cubic Hermite Splines
Introduction In industrial designing and manufacturing, it is often required to generate a smooth function approximating a given set of data which preserves certain shape properties of the data such as positivity, monotonicity, or convexity, that is, a smooth shape preserving approximation. It is assumed here that the data is sufficiently accurate to warrant interpolation, rather than least ...
متن کاملHermite Interpolation Outperforms Nyström Interpolation
Hermite interpolation is shown to be much more stable than Nyström interpolation in the context of solving classic Fredholm second kind integral equations of potential theory in two dimensions using panel-based Nyström discretization. AMS subject classification (2000): 31A10,45B05,65D05,65R20.
متن کاملA Recursive Algorithm for Hermite Interpolation over a Triangular Grid
A recursive algorithm for Hermite interpolation of bivariate data over triangular grids is presented. This interpolation algorithm has a dynamic programming flavor and it computes a single polynomial that interpolates the full set of data. The data we interpolate are partial derivatives and mixed partials up to some fixed order at the nodes of the grid. The interpolant is a polynomial with mini...
متن کاملQuantum Hermite Interpolation Polynomials
Abstract. The concept of Lagrange and Hermite interpolation polynomials can be generalized. The spectral basis of idempotents and nilpotents of a factor ring of polynomials provides a powerful framework for the expression of Lagrange and Hermite interpolation in 1, 2 and higher dimensional spaces. We give a new definition of quantum Lagrange and Hermite interpolation polynomials which works on ...
