Appendix1A_K_hold_out

说明：  有频带方差和谱熵法。自己实现加窗分帧。里面设计傅里叶变换还有矩阵的运算。(speech endpoint detection. frequence_diff and pushang.)

在Matlab环境下生成dll再在vb中调用(in Matlab environment generated dll again in vb Calling)

c++实现UPnP设备发现功能，对初学者非常有用，走出第一步。实现设备发现后，控制功能的原理比较简单，工作量不大。(UPnP device discovery via c++， useful with beginners.it s the first step. After discovery,control is easy and simple.)

实现孤岛检测,在单逆变器或者多逆变器并网运行时，由于故障情况导致的逆变器与主网分离，而产生的不正常现象，可以采用孤岛检测方法实现孤岛检测。(For detecting an island, in a single inverter, or inverter parallel operation, caused by the fault condition of inverter and provids separation, produce abnormal phenomenon, an island detection method can be used for detecting an island)

说明：  用Matlab产生正弦波,矩形波,以及白噪声信号，并显示各自时域波形图 进行FFT变换，显示各自频谱图，其中采样率，频率、数据长度自选 做出上述三种信号的均方根图谱,功率图谱,以及对数均方根图谱 用IFFT傅立叶反变换恢复信号，并显示恢复的正弦信号时域波形图(fft analysis,plot rms spectrum,power density spectrum, etc.)

snake算法的matlab程序，可用于区域跟踪。(snake algorithm Matlab procedures can be used to track regional.)

Edge detection using gradient and laplacian operator

说明：  基于贝叶斯分类算法的图像阈值分割 迭代最佳阈值分割算法 matlab7.0环境运行无误(Bayesian classification algorithm based on image threshold segmentation iterative threshold segmentation algorithm for the best environment to run correctly matlab7.0)

说明：  模糊控制的DCDC变换器，模糊规则按照自己设定的，根据具体情况可以自己设定。(Fuzzy control of DCDC converters, according to their own set of fuzzy rules, can be set according to specific circumstances.)

关于匹配滤波的相关计算，使用matlab编程实现，探讨匹配滤波的一些问题。(matched filter on the relevant calculations, the use of Matlab programming, the matched filter to explore some of the problems.)
