四节点四边形板单元振动模态分析

采用一种快速收敛变步长LMS（Least mean square ） 自适应最小均方算法matlab源程序，其中算法所做的工作是用FIR 滤波器的预测系统，对IIR系统进行预测，如果阶数越高越能逼近被预测系统。(Using a fast convergence of variable step size LMS (Least mean square) adaptive least mean square algorithm matlab source, one of algorithm is the work done by FIR prediction filter systems, prediction of IIR systems, if the higher order the more it can be prediction system approximation.)

◆输入数据： 由键盘输入待查文本文件名和待查单词。待查文件名为：input.txt。 ◆输出数据： 输出文件为output.txt，该文件第一行为该单词在文件中出现的次数。 从每二行开始是依先后次序输出的包含该单词的句子。 (◆ Input data: text file name to be examined by the keyboard input and searching words. Unknown origin file name: input.txt. ◆ Output data: output file output.txt, the first acts of the file of the word the number of occurrences in the document. From the beginning of every second line is output in the order in which the word sentences.)
