A New Way for Cartesian Coordinate Transformation and Its Precision Evaluation

open access: yesRemote Sensing, 2022
High-precision coordinate transformation is vital for high-quality data fusion involving different coordinate systems. The transformation precision is mainly evaluated by the transformation parameters’ estimation precision, the root mean square error ...

Computing hypergeometric functions rigorously [PDF]

open access: yes, 2016
We present an efficient implementation of hypergeometric functions in arbitrary-precision interval arithmetic. The functions ${}_0F_1$, ${}_1F_1$, ${}_2F_1$ and ${}_2F_0$ (or the Kummer $U$-function) are supported for unrestricted complex parameters and ...

A Convolve-And-MErge Approach for Exact Computations on High-Performance Reconfigurable Computers

open access: yesInternational Journal of Reconfigurable Computing, 2012
This work presents an approach for accelerating arbitrary-precision arithmetic on high-performance reconfigurable computers (HPRCs). Although faster and smaller, fixed-precision arithmetic has inherent rounding and overflow problems that can cause errors

Computing periodic orbits with arbitrary precision

open access: yesPhysical Review E, 2011
This paper deals with the computation of periodic orbits of dynamical systems up to any arbitrary precision. These very high requirements are useful, for example, in the studies of complex pole location in many physical systems. The algorithm is based on an optimized shooting method combined with a numerical ordinary differential equation (ODE) solver,
