摘要: 研究矩阵的{1,3}, {1,4}广义逆和对称L-zero矩阵的广义 Bott-Duffin 逆, 这3种广义逆均在多个领域有广泛应用;得到了它们的新表达式和若干代数性质,并举例说明了它们在最小二乘解和极小问题解中的应用.Abstract: This paper investigated three kinds of widely used generalized inverses of matrices: they are {1,3} and {1,4} inverses, and generalized Bott-Duffin inverse of L-zero matrices. Some new expressions and properties are obtained; and examples are given to illustrate their applications in finding least-square solutions and minimum problem solutions.
