考虑具有q0的非线性矩阵方程X+A~*X~qA=I,其中I是(n×n)单位矩阵,A是(n×n)复数矩阵。详细讨论了该方程解的一些性质和基本不动点迭代,并给出了解唯一性的显式公式。通过数值例子说明了结果。
Consider the nonlinear matrix equation X+A~*X~qA=I with q0,where I is the (n×n) identity matrix,A is the (n×n) complex matrix.Some properties of the solution and the basic fixed point iterations for the equation are discussed in some detail,and the explicit formulations about uniqueness of the solution are given.The results are illustratd by numerical examples.
