matlab没有提供画椭圆的函数，该函数在获得椭圆中心 长轴轴 短轴后进行画椭圆，其中使用复变函数(did not draw an ellipse matlab function, the function in the long axis of the axis minor axis of the ellipse center painted oval, which use the complex function)

半带滤波器的matlab实现，实现了2倍抽样的过程。(Half-band filter matlab implementation, to achieve a 2-fold sampling process.)

基于维特比译码算法的BPSK解调方式，survivor_state是一个矩阵，它显示了通过网格的最优路径，这个矩阵通过一个单独的函数metric(x,y)给出，这个算法既能用于硬判决译码也能用于软判决译码。 (BPSK demodulation method based on viterbi decoding algorithm, survivor_state is a matrix, the optimal path of it shows through the grid, the metric matrix through a separate function (x, y), the algorithm can not only used for decoding hard decision can also be used to the soft decision decoding. )

说明：  输出电压稳定不随输入电压、输出侧负载变化而变化，电流电压环pi参数已整定完毕，内外环配合良好。(The output voltage stability does not change with the input voltage and the load at the output side. The PI parameters of the current voltage loop have been set.)

几个MATLAB实现的GUI界面，如多选菜单，可控制小球运动速度的用户界面，函数变换等主要共初学者参考使用！(several MATLAB GUI interface, such as more election menu control the ball movement speed of the user interface, the main function transform a total beginners reference!)

tutorial, matlab, genetic algorithm

说明：  电机定子绕组故障，它可以准确诊断定子绕组故障(Stator winding fault, it can be accurate diagnosis of stator winding fault)
