三、离散型加权余量法前已指出,配点法在计算中不需要作繁琐的积分计算,它属于离散型的加权余量法,由于它原理简单而又十分适于电子计算机的计算,所以很受大家的重视。这类以配点法为主的方法,还有最小二乘配点法或叫离散型最小二乘方法以及正交配点法,最近国内还提出了高斯配点法及配点与配线的混合法。下边首先进一步讨论配点法,然后重点介绍最小二乘配点 Third, the discrete weighted residue method has pointed out that the collocation method does not need to do cumbersome integral calculations in the calculation, it is a discrete weighted residual method, because it is simple and very suitable for computer computing, so It is very much everyone’s attention. Such collocation-based methods include the Least Square Collocation Method or the Discrete Least Squares Method and the Orthogonal Collocation Method. Recently, the Gaussian collocation method and the hybrid method of collocation and wiring have also been proposed. Below, we will first discuss the collocation method first, and then focus on the least squares collocation.
