Invers Matriks Leslie Bentuk Khusus Ordo n×n (n≥4)

This study aims to determine the inverse of the Leslie matrix of special order n × n ( n ≥ 4) using the Adjoin method. There are three steps to do. First, note the shape of the determinant pattern of the Leslie matrix of special shapes of the order 4 × 4 to 10 × 10 so that the general form is obtained. Second, consider the shape of the cofactor matrix pattern of the Leslie matrix in the special form of the order 4 × 4 to 10 × 10 so that the general form is obtained. Third, the general form of the inverse of the Leslie matrix of the special form of order n × n is obtained based on Theorem 3.1 regarding the general form of the determinant and Theorem 3.2 relating to the general form of the cofactor.
