block tridiagonal matrix meaning in English
块三对角矩阵
块三对角阵
Examples
- The inverse of a class of block tridiagonal matrices is investigated
摘要讨论了一类块三对角矩阵的求逆问题。 - With the lu decomposition of the block tridiagonal matrix , an explicit expression of the block inverse elements is obtained
由块三对角矩阵的lu分解，得到了其逆矩阵块元素的显式表达式。 - A relation between the inverse elements is found , and a new algorithm for inverting a block tridiagonal matrix is established
当考虑该表达式的结构特徵时，可得到块元素的递推关系式，由此得到一个求逆矩阵的新算法。
