摘要
分析了离散卷积，离散相关，离散傅氏变换的矩阵形式，以及各矩阵形式间存在着密切的关系。并利用离散卷积和离散傅氏变换的矩阵关系，证明了循环矩阵逆阵的求解公式。
This paper analyses the matrix representation of discretion convolution,discretion correlation,discretion Fourier transformation and their relations.According to these relations,we proved the formula for evaluating the inverse matrix of a cyclic matrix.In fact,these relations can be used in solving other cylic matrix problem.
