We consider a class of inverse positive matrices, which is called Maximum inverse positive (MIP) matrices. If A is an MIP matrix, then for any matrix B which has at least one entry larger than that of A, then B is no longer an inverse positive matrix. Some existence and nonexistence results for MIP matrices are presented.
