说明：  以下程序是基于matlab软件实现自适应滤波器的lms和rls两种算法，不像有些程序那样冗杂，简练明了。定义一个输入信号加入一组噪音，用自适应算法进行滤波，其中用到一个for循环。
(The following procedure is based on the matlab software implementation of the LMS adaptive filter and rls two algorithms, unlike some of the procedures as miscellaneous, concise and clear. The definition of an input signal by adding a group of noise, use of adaptive filtering algorithm, which uses a for cycle.)
