QtW

该代码是自己编制的，主要用于红外图像的特征提取，其中提取长宽比，复杂度，紧凑度，均值比，不变矩等七种红外图像的特征，可很好的为以后的识别做准备(The code is compiled their own, mainly for the infrared image feature extraction, which extract the aspect ratio, complexity, compactness, mean ratio of seven invariant moments and other characteristics of infrared images can be very good for the future identification prepare)

说明：  用matlab程序仿真QPSK系统中调制、解调，懂得QPSK通信系统的真正内涵(QPSK simulation with matlab program system modulation, demodulation, QPSK communication system to understand the real meaning of)

模式识别，聚类分析中的fuzzy_k_means算法。经调试可用。希望有用~(Pattern recognition, cluster analysis fuzzy_k_means algorithms. After debugging available. I hope useful ~)

心电信号预处理，去除肌电信号，工频信号，肌电漂移的影响(ECG signal preprocessing,removal of EMG signals, frequency signals,and electromyographic drift.)

matlab7.0没有这个函数，求举矩阵的最大最小值问题，下载后放在work目录下即可调用(mapminmax.m function)

tangent bug is usefull for use it

说明：  光伏并网逆变器的仿真以及参数的设定，采用传统配置(inverter Simulation of photovoltaic grid-connected inverters and parameter settings using traditional configurations)

说明：  matlab 和c或者c++ 接口程序，采用mex技术和matlab 计算引擎方式，可以提高matlab运行效率(matlab and c or c++ interface program using matlab calculation mex engine technology and methods can improve the operating efficiency matlab)
