Multiquadric surfaces in C

Computers & Geosciences, 1994
Abstract Hardy's multiquadric method is used as a basis for fitting irregular, continuous surfaces where z = f ( x , y ). Four stages are involved in the implementation of the method: (1) solution of a system of simultaneous, linear equations; (2) interpolation of new z values, using a multiquadric equation, for any number of locations within ...

Multiquadrant digital analysis of shoulder capsular thickness

Arthroscopy, 2000
Abstract Purpose: Nonablative thermal capsular shrinkage has been developed in an attempt to address the plastic capsule deformation thought to cause increased rates of recurrent instability following arthroscopic stabilization procedures.

Repeated Knots in Least Squares Multiquadric Functions

1995
A previous paper by the authors [2] noted that there was a strong tendency to obtain near-repeated knots in their algorithm for least squares approximation of scattered data by multiquadric functions. In this paper we observe that this leads naturally to the inclusion of derivatives of the multiquadric basis function in the approximation, and give an ...

Convergence of Univariate Quasi-Interpolation Using Multiquadrics

IMA Journal of Numerical Analysis, 1988
Quasi-interpolants to a function f: \(R\to R\) on an infinite regular mesh of spacing h can be defined by \(s(x)=\sum^{\infty}_{j=- \infty}f(jh)\psi (x-jh),\) (x\(\in R)\), where \(\psi\) : \(R\to R\) is a function with fast decay for large argument. In the approach employing the radial-basis-function \(\phi\) : \(R\to R\), the function \(\phi\) is a ...
