一 维 时 域 有 限 差 分 法 MATLAB 代 码(One-dimensional finite difference time domain method MATLAB code)

说明：  Hurst参数用来衡量时间序列的相关程度。给出了AVB, R/S, VT, PG, Wavelet等多种方法。(The degree of dependence of a time serie is measured by Hurst paramrter. AVB, R/S, VT, PG, Wavelet methods are given in this package. )

the code for reading .raw file

它可以实现对jpg图像进行人脸检测，最后对原彩色图像中人脸的位置以方框形式显示(It can realize JPG image of face detection, finally to the original color image face position shown in box)

matlab中的循环卷积，DFT,DCT，它在数字信号处理方面有很大地作用(circular convolution in matlab, digital signal processing, it has greatly effect)

主要用于matlab中的一些基本方法的介绍 以一些功能简介，适合初学matlab用户(used for matlab)

leach matlab 源码可用 通过matlab 分析leach 协议(leach matlab)

说明：   基于matlab 的叠加高斯白噪声的正弦信号频谱分析，给定正弦函数x=sin(2πf0n/N+π/3)+sin(2πf1n/N+π/4)，设定f0.f1的值，加了噪声之后做快速傅里叶变换，在matlab中分析其频谱，验证是否与f0,f1的值符合。再变换N值，看随着N值的变化对应点是否符合及有何变化。(Matlab based on the superposition of Gaussian white noise sinusoidal signal spectrum analysis, given the sine function x = sin (2蟺f0n/N+蟺/3)+sin (2蟺f1n/N+蟺/4) set value of f0.f1, do a quick noise Fourier transform to analyze the spectrum in matlab, verify that with f0, in line with the value of F1. Transform the value of N, see change as the value of N corresponding points of compliance and what changes.)

说明：  这个TIMEIT Benchmark用来统计用户算法的性能，只需要将你的函数句柄传递给TIMEIT.M，它就会算出循环次数等。(This TIMEIT Benchmark users for statistical performance of the algorithm, only need to handle your function passed to TIMEIT.M, it will calculate the cycle frequency.)
