电力系统潮流计算 运用MATLAB软件来实现这一功能(Power Flow using MATLAB software to achieve this functionality)

這是一個讓原始音訊可以再不改變音訊長度下，改變pitch的程式，因為如果音訊用resample，雖然可改變其音訊頻率音高，但是卻會有拉長音訊的副作用，因此設計了一個可以改善其缺點的小方法(實做paper ）(This is an original audio so that you can no longer change the audio down the length of the program to change the pitch because if the audio with resample, although it can change the pitch of the audio frequency, but the audio will be stretched side effects, and thus can improve the design of a small way shortcomings (real do paper))

用esprit方法估计功率谱，并估计信号频率和峰值(To esprit methods estimate the power spectrum, and estimate the signal frequency and peak)

matlab实现lsqr算法的源码，有强烈的参考价值，可用于地球物理反演。(matlab realize lsqr algorithm source code, there is a strong reference value, can be used for geophysical inversion.)

使用google gears离线技术来实现的一个小web程序(Use google gears offline techniques to achieve a small web application)

利用枝切法进行相位消跳变（解包裹）；有示例图像。(Elimination phase transition (unwrapping) use branch-cut has sample images.)
