In this paper, generalized inverse of matrices is theoretically summaries with differentexamples and proposes applications. The paper consists of two main parts. The first one is forimportant issues on fundamental theories and the extended parts of generalized inverse. Thesecond part is for different examples and application proposes by the authors in the systemsparameter estimation aspects. The authors hope that readers can avail several ideas and methodsfrom this paper for their further studying in system theory.
