upper triangular matrix

The infinite upper ( lower ) triangular matrix Division ring is discussed.

论文对体上一般的无限上 ( 下 ) 三角阵(不要求是行有限的)进行了研究.

Graded and Ungraded Properties of Polynomial Rings and Special Upper Triangular Matrix Rings

多项式环及特殊上三角矩阵环的分次与非分次性质

Compared with the LUD ( Lower and Upper triangular matrix Decomposition) algorithm which also has high estimation performance, the new algorithm has higher resolution under low Signal-to-Noise Ratio ( SNR) condition, or same resolution under high SNR.

与同样具有高性能的LUD（Lower and Upper triangular matrix Decomposition）算法相比，在低信噪比时新算法的分辨率更高，高信噪比时，二者性能则相似。
