This paper presents a new type of circulant matrices. We call it the first and the last difference r-circulant matrix (FLDcirc_r matrix). We can verify that the linear operation, the matrix product and the inverse matrix of this type of matrices are still FLDcirc_r matrices. By constructing the basic FLDcirc_r matrix, we give the discriminance for FLDcirc_r matrices and the fast algorithm of the inverse and generalized inverse of the FLDcirc_r matrices.
