本软文件是copula的matlab说明和案例，是Word文档。(The soft file is the copula matlab description and case, is the Word document.)

there is some code in matlab that will provide help in the field if digital image processing.it includes the code of extracting region of interst, median filter, nearest neighbour point sampling technique, negative of an image etc. and it is done by myself because i am doing becholar of computer science.it does not include any copyrighted content.i hope it will help thoes people that required help in the field of digital image processing.

通过matlab实现czt频谱细化算法，绘制图形与fft方法进行比较(By thinning algorithm matlab realize czt spectrum, graphing methods were compared with fft)

MSK的MATLAB调制，全过程，很不错，适合毕设的同学(The MATLAB MSK modulation, the whole process, very good for students who complete set)

录制汉语拼音 a1（阴平）的发音。分别提交你所能录制的基音频率最高和最低的两个 录音文件。文件名为: 学号_a_h.wav（高音文件）和学号_a_l.wav（低音文件）。（用MathLab 编程） 1）分别对这两个文件进行观察分析。找出最高和最低基音频率位置，分别显示此时它们的 局部波形和短时频谱（按照最大值为100 归一化显示）。 要求：在时域波形上标出基音周期，并算出数值（精确到一个采样点）。在频域图上标出 基音频率。注意：标出分析波形的起始位置（精确到采样点位置），说明谱分析时所采用 的窗函数。 2）用倒谱分析法，估计语音产生模型的声道传输函数H(w)的模|H(w)|。在1)的频谱图上叠 加显示H(w), （按照最大值为100 归一化显示）。 3）用线性预测分析方法，估计语音产生模型的声道传输函数H( )的模| H( ) |。并在 1) 的频谱图上叠加显示H( ) 。(no no non )

复杂网络的各种模型matable仿真，英文的，英语好的大神可以看看(Complex Network Package)

根据滚动轴承的内圈，外圈，滚动体，正常四方面做故障诊断预处理(According to the fault of rolling bearing inner ring, outer ring, rolling body, the normal four fault diagnosis pretreatment)

In implementing this project, four types of gray wolves like Alpha, Beta, Delta and Omega is the use to simulate the leadership hierarchy in which the three main steps of the hunt, searching for prey, surrounded prey, and attack the bait, are implemented. The simulation results with particle swarm algorithm (PSO) is compared, show that the algorithm has achieved better performance Grey Wolf GWO.
