专业释义

    数学

  • 对称箭形矩阵

    Secondly we consider two kinds of the least-squares problems for inverse problems of symmetric arrow-head matrices,discuss the conditions under which they have solutions,and derive the expressions of the least-squares solutions. The corresponding algorithms are presented to compute the least-squares solutions.
