对角阵 meaning in Chinese
diagonalmatrix diagonal matrix
Examples
- When the measurement noise covariance is certain matrix that can be transformed to a diagonal matrix by matrix resemble transform , the dissertation develops optimal centralized and distributed fusion estimate
对于测量噪声相关矩阵是确定的，且该矩阵可以通过相似变换变成对角阵的多传感器系统，给出了最优集中式、分布式融合估计。 - Thesis [ 36 ] generalized multiplicative noise into a diagonal matrix . but it is also an idealized assumption . the above assumptions are n ' t in accordance with the practical instance in most cases
文献[ 36 ]虽然将乘性噪声推广为对角阵的情况，给出了多通道乘性噪声意义下的最优估计算法，但文章对通道特性做了一种较为理想化的限制。 - The algorithms do not use any pivotal operation , but use the generalized ( e , d ) - active constraint set to determine the generalized projection matrices . the diagonal matrix of the projection matrix is a new construction method and it is the main function to insure the finite termination
算法不使用任何转轴运算，仅用( ， ) ?积极约束集确定广义投影阵，该投影阵中的对角阵是一种新的构造方法，它在保证算法的有限步收敛中起十分重要的作用。 - The explicit method is widely used for its simpleness and little memory consumed with local time step and variable coefficients implicit residual smooth to accelerate the convergence procedure . according to yoon and jameson ' s ideas , an efficient implicit lu - sgs algorithm is carefully constructed by combing the advantages of lu factorization and symmetric - gauss - seidel technique in such a way to make use the l and u operators scalar diagonal matrices , thus the numeric algorithm requires only scalar inversion . the computational efficiency is greatly improved with this scheme
显式方法具有简单，消耗内存小等优点，并采用当地时间步长、变系数隐式残值光顺等加速收敛措施，在定常流动的模拟中得到了广泛的应用;根据yoon和jameson提出的简化正、负矩阵分裂，构造的l 、 u算子只需进行标量对角阵求逆，极大提高了流场数值求解过程的计算效率;采用newton类型的伪时间子迭代技术使时间推进精度提高至二阶。
