矩阵对矩阵的微商与平差结果的方差最小性

The differential Coefficient on Matrix to Matrix and the Minimality of Variance of the adjusted Results

    摘要
  • 摘要: 本文介绍矩阵对矩阵的微商,并应用这种更广义的矩阵微商证明了平差结果的方差最小性,这种证明方法比通常的方法更为严密。

     

    Abstract: This paper introduces the definition of the differential coefficient from matrix to matrix,and applies this more generalized definition to prove the minimality of the variance of the adjusted results.This method of proving is considered to be more rigorous than the usually adopted ones.
