original matrix meaning in Chinese
原矩阵
Examples
- Besides the preconditioning techniques , there arc many other methods to turn the original matrix to a new one of better properties . pre - symmetry is such a kind of technique . cg is stable and efficient , but it can only be used to symmetric matrices
除预条件外，尚有许多其它的预处理技术将原矩阵化为性质较好矩阵，预对称化即是其中之一， cg迭代法不仅效率高，而且稳定性好，但却只能应用于对称矩阵，采用预对称技术将非对称矩阵化为对称矩阵，就能利用cg法进行高效计算。
