利用matlaB语言实现各种算法的实用程序，信号分析处理

This program explain how to get auto-correlation and auto spectral function including crosscorrelation function.

matlab 直流潮流计算程序 DCpowerflow(matlab DC load flow calculation program DCpowerflow)

it is hand simulation in MatLab

1.地球同步轨道卫星，倾角分别为0，30，90度。 (1 satellites in geosynchronous orbit, respectively 0,30,90 degrees inclination.)

用matlab语言编写了一个GUI截面，通过该界面可以实现图像的傅立叶变换，反傅里叶变换，高低通滤波，以及把黑白图像转化成灰度图像等功能。(Matlab language with a GUI section, the interface can be achieved through the Fourier transform of the image, anti-Fourier transform, high and low pass filter, and the black and white image into gray image and other functions.)

Matlab粒子群工具箱，实现优化计算中的粒子群算法功能(The Matlab Particle Swarm toolbox, particle swarm optimization calculation algorithm function)

建立数学模型，求解能量最优条件下的分群数量(现代通信技术)。同构网络、同构网络、N节点随机部署，网络范围A*A；距离sink较远，认为所有点到sink距离相等。(A mathematical model, solving the energy clustering under optimal conditions the number of (modern communication technology). Homogeneous network, homogeneous network, N nodes are randomly deployed network-wide A* A far from the sink, that all points equidistant to the sink.)

This is a MATLAB implementation of the SIFT keypoint detector and descriptor (do_gaussian: generate Gaussian scale space of input image do_diffofg: generate Difference of Gaussian (DoG) scale space do_localmax: local extrema as the potential keypoints do_extrefine: refine the keypoints by discarding the ones with low contrast and along an edge do_orientation: compute the orientation of a support region of keypoint do_descriptor: compute the descriptor of a keypoint based on image gradients. do_match: match two images based on the nearest neighbor principle and spatial consistency. do_sift: generate the SIFT descriptors for a given input image. It basically s all the functions above. )
