| 摘要: |
| 本文针对对称矩阵A建立起性态数的并行计算公式，并通过数值试验得到了矩阵性态数变化对方程组Ax=b的解的误差影响，同时进行了向量和标量计算，计算结果表明：当n大于等于300时，向量计算速度比标量计算速度快17倍。 |

| Abstract: |
| A parallel computing formula for the conditional number of symmetric matrix A is presented.the facts for The change of the conditional number of symmetric matrix A affecting the solution of Ax=b are observed. The results of the computation show that the velocity for vector computation is 17 times faster than that of scalar computation with n≥300. |
