A note on (m,l) idempotent matrices

摘要：

Zhang wei presents a necessary and sufficient condition for (m,l) idempotent matrix by the power of its minimal polynomials concomitant matrix. This paper studies the relation between the degree of the minimal polynomial of (m, l) idempotent matrixA and its rank index firstly. As an application, we point out that the corresponding result obtained by Zhang wei is incorrected.
