说明：  matlab教科书第十章程序实例，内涵45个程序，绝对实用，程序中都有中文注解(Chapter textbook example matlab program, meaning the 45 procedures, the absolute utility, the program has Chinese comments)

高斯混合模型对目标说话人识别的matlab源程序(Gaussian mixture model of the target speaker recognition matlab source)

matlab中编写的船舶动力定位PID控制函数，适于DP建模动态模拟分析(written in matlab，Ship Dynamic Positioning PID control function, suitable for DP dynamic simulation modeling )

Matlab计算信噪比,单声道，双声道均可，公式准确程序清晰(Matlab calculation of signal to noise ratio, mono, dual-channel may be, the formula clear and accurate procedures)

应用matlab对负责数学模型分析求解方法解析(Application the matlab responsible mathematical model analysis method for solving resolution)

making exponential signal with matlab In communications, the purpose of using exponential signals instead of sinosuid ones is to use both halves of signal spectrum(Negative and Positive sides of spectrum). For example an FSK signal can not simply downconverted to DC. because its spectrum is not symmetric around its center frequency, so you should downconvert it with exponential signal( the idea of using I and Q downconverter).
