| Abstract: | In this paper,the concept and algorithm of extremal sparse matrix and its J inverse matrix is established.Then,in linear programming problem with a change of instructural parameters,an iterative algorithm to calculateB+ΔB]~(-1) from known B~(-1) is discussed. It especially applies to ΔB containing continuous change parametrics. |
