摘　　要：　求逆矩阵通常的方法是初等变换法或伴随矩阵法,计算量大且容易出错,本文利用循环矩阵的特殊性质给出了一类特殊循环矩阵求逆的计算公式,简化了一类特殊循环矩阵求逆的计算.The ordinary methods of matrix inversion are elementary traslation or associat matrix. A large amount of calculation is required, which is subject to produce errors in the procedure. Based on the special charicteristics of circulant matrix, a new formula of inversion for a type of specific matrix is proved in this paper. As a result, this method simplifies the process of matrix inversion.
