使用matlab调用ansys完成优化分析(Call use the matlab optimization analysis ansys)

ukf滤波器实现代码 有利于初学者了解非线性滤波变成(ukf Filter beneficial for beginners to understand the code into a non-linear filtering)

说明：  这是一本关于matlab的教程，同时也是一本信号处理的教程，其特点是将matlab用于信号处理(This is a tutorial on matlab, but also a signal processing tutorial, and its characteristic is used in signal processing matlab)

1 录入一段语音，对其进行时域频域处理，通过变频、变速达到变声目的，且使处理后的语音信号不影响正常收听与理解。 2 用图形用户界面（GUI）对上述变声前变声后进行时域频域图形输出，不同的频率、速度有不同的输出，且对前后波形进行比较 (1 entry a voice, the frequency domain and time domain by frequency conversion variable speed, processing to make the treatment and voice purpose, after the speech signal shall not affect the normal to listen to and understand. 2 with the graphical user interface (GUI) voice of the above voice before after the frequency domain in the time domain graphics output, different frequency, speed have different output, and compared before and after waveform )

一个对时间反转镜技术的原理的简单的描述和仿真。(a simple description for the TRM )

正弦周期信号的随机共振，不同于以往微弱信号检测中的抑制噪声，随机共振能通过噪声加强信号传输能力( We present the numerical method to solve the bistable SR model based on Runge-Kutta algorithm, and propose a new kind of approach for detecting weak signal, which can effectively detect both period and aperiodic weak signals corrupted by the strong noise background. )

石油测井解释单孔隙度分析程序POR源程序 可计算地层孔隙度、地层含水饱和度、渗透率、泥质含量等参数；划分砂泥岩剖面；判断油气水层 (Oil log interpretation porosity analysis program POR single source Calculate formation porosity, formation water saturation, permeability, clay content and other parameters divided sand shale section determine gas-water layer)

FKCM图像分割算法的Matlab程序。希望对大家有所帮助。(Image segmentation algorithm FKCM program Matlab. We want to help.)

说明：  主要包括两个源代码。其中一个源代码是识别程序的，另一个是一个矩阵类库的。(Consists of two source code. One is to identify the program source code, and the other is a matrix class library.)
