1 录入一段语音，对其进行时域频域处理，通过变频、变速达到变声目的，且使处理后的语音信号不影响正常收听与理解。 2 用图形用户界面（GUI）对上述变声前变声后进行时域频域图形输出，不同的频率、速度有不同的输出，且对前后波形进行比较 (1 entry a voice, the frequency domain and time domain by frequency conversion variable speed, processing to make the treatment and voice purpose, after the speech signal shall not affect the normal to listen to and understand. 2 with the graphical user interface (GUI) voice of the above voice before after the frequency domain in the time domain graphics output, different frequency, speed have different output, and compared before and after waveform )

使学生通过本实验，从几何直观观察几种插值方法的特点和不同插值效果，进一步理解方法的应用背景和适用范围。从而加强和巩固学生的理论知识，提高分析问题，解决问题的能力，提高理论知识的应用能力及计算机编程能力。(Students through the experiment, visual observations from the geometric characteristics of several interpolation methods and different interpolation effects, and further understand the methods of application of the background and scope of application. In order to strengthen and consolidate the students the theoretical knowledge and enhance their analysis of issues, problem-solving abilities, improve the application of theoretical knowledge, ability and capacity of computer programming.)

DS-CDMA仿真程序,有大量注释,很值得一看,全面的讲解了CDMA的原理.(DS-CDMA simulation program, has a large number of notes, it is worth a visit, a comprehensive explanation of the principle of CDMA.)

The REMUS simulator program was written using MATLAB. The first program, REMUSSIM.m,loads the vehicle initial conditions and tracks the vehicle state. The second program, REMUS.m,calculates the new vehicle accelerations based on the vehicle state and control inputs.

说明：  最小二乘法辨识电池参数，适合参考，希望对电池研究人员有帮助(Identification of battery parameters by least square method)

this is code for human mouse interfacing
