其中,Normalized Least Mean Squares(NLMS)算法作为Least Mean Squares(LMS)算法的一种改进,具有更快的收敛速度和更好的稳健性。本文将详细介绍NLMS算法的原理,并通过MATLAB进行仿真验证。 算法原理 NLMS (Normalized Least Mean Squares) 是LMS (Least Mean Squares) 算法的一种改进。与LMS算法相比,NLMS算法具有更快...
least_squares解超定方程组python 本文针对n个未知数,大于n个方程组。求解未知数的问题,matlab代码。 一、首先,请注意,本文说的是线性超定方程组,方程组是线性的,不含有未知数的出发以及乘方。 求线性超定方程组,有这么几种方法: 1. 直接法 2. QR分解 3. SVD分解 4. 迭代法 本文首先选用直接法求解线性方程...

The Moving Least Squares algorithm is a deformation technique that allows to compute a map f:R2->R2 from the transformation of a set of N pivot points p in the new positions q. The map f is smooth (f in C2), preserves the identity (for q=p the map is the identity) and ensures ...
