Figure 4a shows the absolute numerical error of the CZT–ICZT procedure (see Methods) for 16-point contours on the unit circle. Fig. 4b shows the same plot, but with the numerical error predictions superimposed in red (see Eq. (21)). The horizontal axis corresponds to the polar angles ...
Numerical Methods for Roots of Polynomials - Part II 10.1.4 Rounding Errors John (1967) analyses the effect of rounding error in the case of a linear equation p(z)=z-ζ1. Without errors, the xi satisfy xj+1-xjζ1=0. Suppose that the relative rounding error is bounded by ϵ i.e....
不论是否解决了问题,给予反馈,比如“之前问的Inaccurate quadrature in CalDSu的问题,用了scf=novaracc 确实解决了问题。”这为后人和旁观者的学习十分有利,也是一种对帮助的回馈。如果你的问题使用了自己查到、想出的方法解决了,则与人分享就增加了整个社区的知识总量,对自己也常在撰写解决方法的过程中学到更多东西...

Step error calculation of numerical control (NC) machining tool path is a premise for generating high-quality tool path and promoting its application. At present, iterative methods are generally used to calculate step error, and the computation time increases when accuracy improves. Neural networks ...
However, by analyzing the error in more detail, we are able to prove supra-convergence and show that the method is second order convergent regardless of the non-uniformity in the mesh关键词: Maxwell equations convergence of numerical methods error analysis finite difference time-domain analysis ...
