(Decentralized Fused Covariance Type Kalman Filter)

数值分析程序中的一个例子，matlab gui编程(Numerical analysis of an example program, matlab gui programming)

说明：  基于MATLAB的信号与系统仿真课件 基于MATLAB的信号与系统仿真课件需在MATLAB环境下运行，需运行本软件， 请先进入MATLAB，然后键入主程序名main.m(MATLAB-based signal and system simulation courseware MATLAB-based signal and system simulation courseware required to run in the MATLAB environment is required to run this software, please enter the MATLAB, and then type the name of the main program main.m)

自己写的一个计算时频分布的程序,可知指定Cohen类分布类型WVD，CWD，PWVD(Himself wrote a calculation procedure for time-frequency distribution shows the distribution of the type specified Cohen category WVD, CWD, PWVD)

2代小波示意程序-此程序用提升法实现第二代小波变换-我用的是非整数阶小波变换-采用时域实现,步骤先列后行(2 Generation Wavelet indicated procedures- This procedure is used to upgrade method second generation wavelet transform- I use a non-integer order wavelet transform- time-domain implementation steps first column underwent)

说明：  随机信号的提取，通过matlab实现微弱信号的提取(Random signal extraction, through matlab to achieve the extraction of weak signal)

小波变换用计算机的快速实现，采用MATLAB计算工具(Wavelet transform fast to achieve using the computer，Using MATLAB calculation tool)

用FDTD解决一维电磁场传播问题的MATLAB实现(Solve one-dimensional electromagnetic field propagation using the FDTD)

耳蜗实质上相当于一个滤波器组，耳蜗的滤波作用是在对数频率尺度上进行的，在1000HZ下，人耳的感知能力与频率成线性关系；而在1000HZ以上，人耳的感知能力与频率不构成线性关系，而更偏向于对数关系，这就使得人耳对低频信号比高频信号更敏感。Mel频率的提出是为了方便人耳对不同频率语音的感知特性的研究。频率与Mel频率的转换公式为(Cochlear substantially equivalent to a filter set, cochlear filter is used on logarithm frequency scale, under the 1000 hz, the perception of the human ear and a linear relationship with frequency In more than 1000 hz, the perception of the human ear does not constitute a linear relationship with frequency, and prefer to logarithmic relationship, which makes the human ear is sensitive to low frequency signal is better than high frequency signal. Mel frequency is put forward in order to facilitate the ear of the study of speech perception characteristics of different frequency. For frequency and Mel frequency conversion formula )
