Analysis of generalized inverse matrix inversion

In this paper, from a linear objective function, using the singular value decomposition method to calculate generalized inverse matrix and add appropriate damping, using iterative method for solving overdetermined equations directly, the improvement of generalized inverse matrix inversion is realized. Further from the combination of theory and practice it is clarified that the generalized inverse matrix inversion method is flexible and stable, it covers the advantages of multiple inversion method, but also has its own characteristics, in fact adaptability is strong; it can provide some auxiliary information, can better evaluate interpretation results.
