自己编写的MATLAB函数，实现对图像的旋转。B是原图像，灰度或彩色，alpha是旋转角度（角度或弧度单位均可），A是旋转后图像。旋转后图像信息尽可能不损失。(I have written MATLAB function, to achieve image rotation. B is the original image, grayscale or color, alpha is the angle of rotation (degrees or radians per unit), A is rotated images. Rotation after the image information as possible without loss.)

a new circuit topology of a phase-locked loop that can be used for synchronising a singlephase wind turbine generator (WTG) with the low voltage utility grid. The circuit is based on the time-delay digital tanlock loop (TDTL) architecture and was modelled and simulated using Simulink/MATLAB. The results presented demonstrate the ability of the circuit not only to synchronise a WTG with the grid, but also to re-gain synchronization following a sudden disturbance in the grid voltage. The simulated disturbances included a ramp and a multi-step change in the phase of the grid voltage waveform.

Using spectra to calculate strength of reflections and losses in passive cavities.The wavelength, reflection spectrum and transmission spectrum should be in the first 3 columns of an Excel file, which is selected when the cavity.m Matlab file is run.

C++ version (OpenCV) of the Matlab built-in function filtfilt.m.

说明：  此源码进行图片灰度值的处理，使图片更清晰，或者让其变成纯黑纯白(this code does the image gray level enhancement)

说明：  序列x(n)的Bartlett法功率谱估计 用matlab实现(sequence x (n) Bartlett power spectrum estimation method used to achieve Matlab)
