Generalized inverse of the sum of two matrices can be obtained if the range space of the sum of two matrices is disjoint. At the end of the discussion, an example of how to get a generalized inverse matrix is givenothergeneralized inverseaddition properties on ranksrank factorizationthe sum of two matricesOther
