说明：  一个闭环的SVPWM控制，可以稳定控制电机作为毕业设计用(A closed loop of the SVPWM control, stability control motor can be used as a graduation project)

[WuYuFei]中是WuYuFei的论文 [WuYufei_matlab]是WuYufei的Matlab程序 做Turbo码，恐怕很难绕过WuYufei的程序，呵呵 [cap_turbo]和[mother]是我在研究阶段的工作 走了很多弯路，所以这两个目录必然有很多错误而且很混乱 如果想了解一下我的研究历程可以看看，切不可拿来修炼，否则走火入魔俺不管。平，mdsvl,sdlxcl([WuYuFei] is WuYuFei papers [WuYufei_matlab] is a Matlab program to do WuYufei Turbo codes, it would be difficult to bypass WuYufei procedures, Oh [cap_turbo] and [mother] at the research stage of my work take a lot of detours, so These two directories must have a lot of mistakes and a lot of confusion if you want to know can see my research process, must not be used practice, or whether I possessed by the Devil.)

射频技术上的一些MATLAB实现的例题 希望对大家学习RF技术有帮助(RF)

用极限稀疏矩阵对图像分类，该方法快速简单，代码少，效果好(An ultimate sparse matrix for image classification, the process quick and easy, less code, the effect is good)
