Introducing a class of generalized fibonacci sequences with double variables , we establish the relation with aitken , secant , new - raphson , halley transformation etc . , generalize the results of many authors . furthermore , we give a more general generalization of q - matrix 通過引入一類雙變量的廣義fibonacci序列,建立了其與aitken 、 secant 、 newton - raphson 、 halley等變換的關系,進而給出了q -矩陣的一個更廣泛的推廣。

For the purpose of saving running time of iterations , this paper apply adaptive method to aitken extrapolation algorithm and eigenvalues - based algorithm respectively . experimental results elementarily show that these two new algorithms can speed up the performance of iterations 本文將adaptive方法分別與基于特征值直接求解算法和aitkenextrapolation算法相結合,實驗結果初步證明了這兩個新算法能夠縮短迭代時間。

Compared with aitken extrapolation , eigenvalues - based algorithm bypass aitken transform and perform more effectively than aitken extrapolation algorithm theoretically in the process of iterating hyperlink - based markov matrix 與aitkenextrapolation算法相比,基于特征值求解的算法不借助aitken變換,而通過特征值直接求解馬爾可夫超鏈接矩陣的主特征向量,從理論上比aitkenextrapolation算法更高效。

Extrapolation method , composed of aitken extrapolation and eigenvalues - based algorithm mainly , can notably reduce iterations commonly . aitken extrapolation algorithm use aitken transform to reduce iterations Aitkenextrapolation算法使用aitken變換以減少迭代次數,但aitken變換在多數情況下無法確保算法收斂。

In the southern hemisphere of the moon ' s far side , mission scientists saw an unusual signature of high - iron rocks in the floor of the south pole ? aitken ( spa ) basin , the largest basin on the moon 科學家在月球遠地面南半球的南極?艾肯盆地(簡稱spa盆地,是月球上最大的盆地)底部,發現高鐵巖石的異常蹤跡。

Because aitken transform can not converge in many conditions , this paper presents an improved algorithm fnn - aitken extrapolation algorithm by analysis the reason of instability 為了彌補該算法的缺陷,本文在分析了該算法不穩定性的根源后提出了改進算法fnn - aitkenextrapolation 。

Instead of calling aitken transform repeatedly , the improved algorithm call aitken transform in choosing proper occasion only once 與原算法相比,改進算法不頻繁調用aitken變換,而執行選擇適當時機對aitken變換調用一次的策略。
