Abstract:

This paper deals with  the verification for minimum 2norm solutions of underdetermined nonlinear systems. The minimum 2norm solution of underdetermined nonlinear system is the minimum point of the 2norm of solution vectors. For the given undetermined nonlinear system,  combining the verification for simple solutions of square systems with the verification for symmetric positive definite matrices presented an algorithm for verifying minimum 2norm solutions of underdetermined nonlinear systems with full rank Jacobian matrices.

Key words: underdetermined system, minimum 2norm solution, verification
