cepstral analisys for pitch and F0 detection

This function resamples the images at the new grid points defined by the new pixel sizes. It assumes that intensities are defined at the pixel centers

说明：  OFDM的QPSK仿真程序，里面只有一个txt文件，所有程序都在上面了。(OFDM QPSK simulation program, only a txt file, all proceedings in the above.)

数据统计分析功能多个例子在matlaB中的实现，压缩包里面包含讲义和源代码。(Data statistical analysis function number of examples in MATLAB to achieve compression package contains the lecture notes and source code.)

此程序主要功能是 1 画出标准零阶贝塞尔函数， 2 在估计多普勒时，接收信号的实部或者虚部的自相关函数接近于贝塞尔函数，所以画出了一条接近于贝塞尔函数的曲线图(The main function of this program is 1 shows the standard zero-order Bessel function, 2 estimate the Doppler, the autocorrelation function of the received signal or the imaginary portion of the real part close to the Bessel function, so to draw a graph of the Bessel function is close to)

Least_Square method of machine learning

有关matlab并行以及分布式运算的书籍，适合初学者使用。(About matlab parallel and distributed computing books for beginners to use.)

说明：  参考维基百科（https://en.wikipedia.org/wiki/Variance-based_sensitivity_analysis）的取样过程以及对应的Estimators。理论性的东西就不进行复述了，这里主要阐述用MATLAB（R2018b）对某个特定函数进行Solo indices敏感性分析的过程。大致可分为四个过程：采样，构建函数，函数输出（将样本带入函数得到输出值），计算Sobol指数（估算一阶影响指数和全局影响指数）(Sobol global sensitivity analysis)

压缩传感，MATLAB，图像重建，正交匹配追踪，打破乃奎斯特定理，图像分块处理(Compressed sensing, MATLAB, image reconstruction, orthogonal matching pursuit, breaking the Nyquist theorem, the image block processing)

DC-DC和DC-AC仿真，matlab实现(DC-DC and DC-AC simulation, matlab implementation)
