矩阵是数学中一个十分重要的概念，其应用能够十分广泛，Matlab中最基本最重要的功能就是进行矩阵运算，其所有数值功能都已矩阵为基本单元来实现，掌握Matlab中的矩阵运算是十分重要的(Matrix and its operation)

利用相关的瞬时值通过在工作过程中的逐步调整参数逼近信号的统计特性，实现最优滤波。由此，我们得到一种最常用的算法——最小均方算法，简称LMS算法。(By using the instantaneous value of the correlation operation of the progressive approximation of the statistical properties of the signal to adjust the parameters to achieve optimal filtering. Thus, we get one of the most commonly used algorithms- the minimum mean square algorithm, called LMS algorithm.)
