自己用Matlab写的FFT的代码，主要是为了FPGA实现的前期建模(FFT using Matlab to write their own code, mainly to preliminary modeling of FPGA implementation)

介绍了matlab在工程应用方面的使用和方法(Matlab introduced the use in engineering applications and methods)

完整的CDMA各种参数的仿真，包括上行链路的BER，多径干扰下的BER，多径下用户数目的BER等(integrity of the CDMA simulation of various parameters, including the uplink BER, multi-path interference under the BER, Drive over the next number of users, such as BER)

最短路径寻址,用于寻找最短路径，根据实时信息(shortest path )

说明：  Matlab版本代码，主要研究数字水印的DCT算法(Matlab version of the code, the main algorithm of digital watermark DCT)

说明：  关联规则分析问题的一种方法 apriori在MATLAB下的编写 (Association Rules in a way the problem apriori prepared under the MATLAB)

将从地震勘探工程标准格式的segy文件读出的数据重新写成segy格式，方便用专业的软件进行继续处理。(Reading data seismic engineering standards segy file formats out of the rewritten segy format, easy to use specialized software to continue processing.)

Step 1: Set i=1 FA=f(a) Step 2: while i≤ No do step 3-6. Step 3 set p=(a+b)/2 FP=f(p) Step 4 if FP<TOL or (b-a)/2<TOL then OUTPUT(p) STOP. Step 5 set i=i+1 Step 6 if FA.FP > 0 then set a=p FA=FP else set b=p. Step 7 OUTPUT (‘Method failed after No iteration,No=’, No) STOP.

说明：  实现了循环卷积的运算，但是只有结果，没有过程(Cyclic convolution operation realized, but only a result, no process)
