DV-hop是无线传感器网络中用于定位的一种算法，经调试该程序可以通过。(DV-hop wireless sensor networks for positioning algorithm, the debugging of the program can be.)

2013年“高社杯”数学建模b题，对于纵向切割的图片复原。 使用方法：打开matlab，调整工作目录为解压后的文件夹，在matlab工作框中输入Problem1即可(2013 " High Society Cup" Mathematical modeling b title picture for longitudinal cutting recovery. How to use: open matlab, adjust working directory is unpacked folder work in matlab can enter Problem1)

这是自己编的光谱分析程序，里面含有实验数据，下载后请不要当做自己的实验数据，可以作为参考，谢谢合作(This is their series spectral analysis program, which contains experimental data, as their own experimental data Do not download, can be used as reference, Thank you for your cooperation)

Matlab工具箱 - 《复分析基础及工程应用 第3版》，这是书中所带工具箱，与Matlab本身的复分析工具箱相背相比，更适用于教学。(Matlab Toolbox- Fundamentals of Complex Analysis with Applications to Engineering and Science the 3rd version,compared with the similar toolbox of matlab,this toolbox is good at teaching.)

numerical method for averaging

寻找一维或者二维数据的极值点，并将极值点在途中标注出来(find the extrimas in a one dimensional or two dimensional data，and simbolify the extrimas)

实现了PCM编码->基带码型转换（NRZ to HDB3）->QPSK调制->高斯信道->QPSK解调->基带码型反转换（HDB3 to NRZ）->PCM解码。同时给出了误码率曲线。(Achieve a PCM coding-> Baseband code converter (NRZ to HDB3)-> QPSK Modulation-> Gaussian channel-> QPSK demodulator-> anti-baseband conversion pattern (HDB3 to NRZ)-> PCM decoding. Also shows the BER curves.)

matlab图像处理常用程序：线性变换、非线性变换、图像锐化、边界追踪、中值滤波器(matlab image processing program used: linear transformation, a nonlinear transformation, median filter, boundary tracking, image sharpening)

说明：  基于MATLAB和DSP实现的FIR数字低通滤波器(Implementation based on MATLAB and DSP FIR digital low-pass filter)
