Fast algorithm of minimal norm least square solution for Cauchy linear system;2. For the m×n Cauchy-type matrix with full column rank,the fast algorithm of the minimal norm least square solution to the linear system Cx=b was obtained by construction of a special block matrix and study of the triangular decomposition.

对于秩为n的m×n阶Cauchy型矩阵C，通过构造特殊分块矩阵并研究其三角分解，进而得到了线性方程组C x=b的极小范数最小二乘解的快速算法，所需运算量为O+O(n2)，而通常构造法方程组的方法所需运算量为O(m n2)+O(n3)，用正交化法虽然避免了构造法方程组，但所需的运算量更大些。

In chapter four, the dissertation analyses different types of the symbiosis relationship between the independent college and its matrix school from the dimensions of organization and behavior, namely point symbiosis, intermittent symbiosis, constant symbiosis, integration symbiosis, parasitism, commensalism, symmetric mutualism and dissymmetric mutualism. It establishes twenty eight symbiosis morphologies between the independent college and its matrix school. What\'s more, it puts forwards two basic modes for the independent college\'s evolution, and has empirical studies on two typical cases.
