乘冪法求矩陣特征向量與特征值的初始向量及循環(huán)控制 - To some eigenproblems , the corresponding ritz vectors always converge very slowly even sometimes do n ' t converge when ritz values have converged . so in order to improve the convergence of ritz vectors , firstly , refining - strategy is applied to the davidson method in this paper . the process restarts with the refined ritz vectors as the initial vectors , and then we get the refined block davidson method
為了改善ritz向量的收斂性，本文首先在塊davidson方法的執(zhí)行過程中，運(yùn)用精化策略，求出相應(yīng)的精化向量并將其作為初始向量進(jìn)行重新開始過程，由此得到了精化塊davidson方法，并對精化塊davidson方法進(jìn)行了收斂性分析；其次，本文將精化塊davidson方法結(jié)合收縮技術(shù)，提出了收縮的精化塊davidson方法。 - This algorithm easily escapes from local optimal solution , have high searching efficiency , simple structure , convenient use . aiming at iteration , optimization and matlab optimization toolbox having low precision and difficulty to choose initial vector on acquiring nonlinear equations ’ solutions , equations ’ solution problem is translated into genetic algorithm optimization problem . nonlinear equations ’ usual genetic
針對迭代法、最優(yōu)法、 matlab最優(yōu)化工具箱求解非線性方程組中存在求解精度不高及初始矢量難選等問題，將方程組求解問題轉(zhuǎn)化為遺傳算法函數(shù)優(yōu)化問題，建立了非線性方程組通用的遺傳算法解法，并將其用于汽車滑行試驗(yàn)數(shù)據(jù)處理中。 - 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。 - It's difficult to find initial vector in a sentence. 用initial vector造句挺難的
