In the process of computation a method based on mass conservation and a special iteration procedure are applied to accelerate the convergence speed and minimize the error of water balance 在數(shù)值計(jì)算過(guò)程中,采用了質(zhì)量守恒和特殊的迭代求解格式以加快計(jì)算收斂速度和減少水量平衡誤差。
But the theoretical computation of a eigenvalue has some special difficulty . the iteration procedure is likely to diverge in deep subcritical system and lead to calculation failure 但的理論計(jì)算存在特殊的困難,尤其是對(duì)于深次臨界情形,容易發(fā)生迭代過(guò)程不收斂情況,導(dǎo)致計(jì)算失效。
The fractal decoding is a relatively simple iteration procedure , in which the decoded image is approximated by iterating the contractive transformation denoted in the fractal code on an arbitrary initial image 分形解碼是一個(gè)相對(duì)簡(jiǎn)單的快速迭代過(guò)程,解碼圖像由分形碼表示的壓縮變換迭代作用于任意初始圖像來(lái)逼近。
The main part of this hybrid algorithm is a chebyshev iteration which applies chebyshev polynomials to act on initial vectors and makes the obtained vectors close to the wanted eigenvectors ; the second one is the preconditioning subspace iteration method which uses a preconditioning matrix to impact the residual matrix obtained from the iteration procedure , so the distribution of eigenvalues is improved 第一個(gè)改進(jìn)算法是用chebyshev多項(xiàng)式加速的子空間迭代法,它是用chebyshev多項(xiàng)式作用初始向量,使其更接近所要求的特征向量。第二個(gè)改進(jìn)算法是對(duì)每次迭代所得的殘余矩陣直接進(jìn)行預(yù)處理以改善矩陣特征值的分布。
