The operator proof of Ma's matrix inverse
Jianfeng Huang · Journal of Suzhou University · 2005
With an effort to investigate a unified approach to the famous Lagrange inverse,Krattenthaler put forward one kind of operator method and finally found a general pair of inverse relations named Krattenthaler formula. Recently, Ma set up a new unified matrix inversion containing Krattenthaler s and Warnaar s formula as special cases. The present paper reproof Ma's matrix inverse via Krattenthaler s operator method.
