摘要
本文用另一方法证明了非对称矩阵的奇异值是处处强半光滑的,并利用这一性质给出求解逆奇异值问题的相对广义牛顿法,该方法具有Q-二阶收敛速度.
This paper gives an alternative proof that the singular value functions of a nonsymmetric matrix are strongly semismooth everywhere. Based on this property, a relative generalized Newton method is given to solve the inverse singular value problem,which is Q- quadratically convergent.
