实数域上矩阵函数方程的解

Solutions of a matrix function equation on the real field

在f(x)为一般解析函数时,讨论了矩阵函数方程f(X)=A在实数域上有解的充要条件,并由此给出了方程求解的方法步骤。

Let f（x） be a general analytic function over a real field. The necessary and sufficient conditions for solvabili- ty of the matrix function equation f（X） = A are discussed, as well as ways to solve them.
