homogeneous linear transformation

First,the determinant is regarded as a function of or- der n and denoted by D(n);Second,the determinant is expanded by row or by column,then the relation in both of D(n)and subdeterminants will be examined in details to set up certain a recursion,generally speaking,it must be a homogenous or a nonhomogenous recursion;fi- nally the coefficients of the general solution are found out with the aid.

给出了用递归关系方法求任意 n 阶行列式的值的一般方法:首先,把已知的 n 阶行列式看作为阶数 n 的一个函数,记为 D(n);其次,按行或按列展开这个行列式,并仔细观察存在于余子式及 D(n)里的关系,建立关于 D(n)的某一递归关系,此关系总为一个齐次的或非齐次的递归关系;最后,借助于 D(0)、D(1)和D(2)等求出递归关系的通解的系数。
