Matlab实现文本文件读取并存储成矩阵源代码 (这个Matlab程序，可以读取任何文本文件，并返回一个内容的数组。它在执行过程中，对每个字符串进行匹配，每行作为一次匹配的结束。 )

OFDM(Orthogonal Frequency Division Multiplexing)即正交频分复用技术，实际上OFDM是MCM Multi-CarrierModulation，多载波调制的一种。其主要思想是：将信道分成若干正交子信道，将高速数据信号转换成并行的低速子数据流，调制到在每个子信道上进行传输。正交信号可以通过在接收端采用相关技术来分开，这样可以减少子信道之间的相互干扰 ICI 。每个子信道上的信号带宽小于信道的相关带宽，因此每个子信道上的可以看成平坦性衰落，从而可以消除符号间干扰。而且由于每个子信道的带宽仅仅是原信道带宽的一小部分，信道均衡变得相对容易。本程序实现OFDM与QPSK技术的比较(This program realization technology and the OFDM QPSK technology)

lena 图像的线性插值 对图像处理的理解很有帮助(lena bilinear)

Gardner定时算法 matlab仿真。QPSK、16qam，反馈环路(Gardner timing algorithm matlab simulation. QPSK, 16qam, the feedback loop)

声学模态的简正波分析程序，包含很多子程序(The acoustic modal normal mode analysis program contains many subroutines)

说明：  function [ret,x0,str,ts,xts]=s4(t,x,u,flag) s4 is the M-file description of the SIMULINK system named s4. The block-diagram can be displayed by typing: s4. SYS=s4(T,X,U,FLAG) returns depending on FLAG certain system values given time point, T, current state vector, X, and input vector, U. FLAG is used to indicate the type of output to be returned in SYS.
