基于互信息的图像配准，优化算法采用Powell算法，采用matlab编写(Mutual information-based image registration, optimization algorithm uses Powell algorithm, using the preparation of matlab)

利用matlab立体匹配，可获得立体图像左右视图的视差图代码，效果不错 (Matlab matching around view of the three-dimensional image can be obtained disparity map code, good results)

1、 生成多周期线性调频信号，并对其进行频谱分析； 2、 对仿真生成的信号利用两种窗口函数进行STFT变换生成时频分析图(1, to generate multi-cycle chirp signal, and its spectrum analysis 2, the signal generated by the simulation window function using two STFT transform to generate time-frequency analysis chart)

重力异常的向上延拓程序，很实用，，推荐地球物理学生学习可直接使用。 (Gravity anomaly upward extension program, it is practical, and recommended geophysics student learning can be used directly.)

读取SAC格式天然地震数据，可以先读取158字节道头，并且输出NPTS（数字字母码格式），然后开始读取地震数据(Read SAC natural seismic data format that can be read 158 bytes road head, and the output NPTS (alphanumeric format), and then start reading the seismic data)

通过一个单一的合成器实现众多乐器和音效的控制。我们要做的工作就是通过一定的方法合成一段不少于30秒的音乐，并流畅播放。设计中主要采用音调幅度调制的方式再现乐曲。(A number of musical instruments and sound control through a single synthesizer. We work to be done is through the method of synthesis of a period of not less than 30 seconds of music, and smooth playback.The design of the main tone amplitude modulation reproduction of music. )

说明：  确定虚警概率，进行2000次蒙特卡罗实验，将检测成功的概率绘成ROC曲线(Determine the probability of false alarm, conduct 2000 Monte Carlo experiments, and draw the probability of detection success into ROC curve)
