Abstract: By constructing a special class of matrices called M-type matrices, this paper has proved that the sequence gaining from concatenating the rows of a M-type matrix is a bent sequence and therefore generalized the results of [1] and [2].

Key words: Boolean function, Bent function, Walsh-Hadamard matrix, M-type matrix, concatenation, subscripts transformation

摘要： 通过构造一类称之为M-型的矩阵，证明按行下标非退化线性变换的次序级联M-型矩阵的行所得的序列是Bent序列，从而得到了一批Bent函数，推广了R.Yarlardda的结果。
