The inverseleastsquare problem with spectral constraints is also studied and a sufficient condition is given for its solvability.
讨论了四元数量子力学中带有谱约束的最小二乘解反问题,得到了此问题有解的充分条件。

Using the theory of generalized inverse matrix, a perfect algorithm of recurrence for leastsquare has been derived. And from this algorithm, some corollaries of great significance were obtained.
利用广义逆矩阵的理论,本文给出了完整的最小二乘递推算法,并由此得到若干很有意义的推论。

If we use the equation of leastsquare estimator directly, computing amount is often very great because course of computing need calculate the inverse of matrix and multiplication of matrix.
