Vessel model for GNC toolbox

说明：  计算任一语音信号的短时自相关函数，并用画图的形式表现出来，可自定义样本数，和采样频率。方便简洁。(Any calculation of short-time speech signal autocorrelation function, and use the form of drawing out the number of samples can be customized, and the sampling frequency. Easy to clean.)

黄金搜索算法求在区间【a,b】上的最优解(Golden search algorithm for the interval [a, b] on the optimal solution)

用非精确线搜索来求函数极小问题，这种是在一维的情况下的情况(Minimization Problems with inexact line search to seek, this is the situation in the case of one-dimensional)

说明：  matlab 实现文字提取 及正负面分析(Text Classication and Sentimental Analysis)

谱估计的welch算法、周期相关图谱估计算法(Welch spectral estimation algorithm, cycle-related pattern estimation)

采用N=11的标准线阵，进行DOA估计，要求有两个信号。采用MUSIC算法(Standard linear array with N = 11, DOA estimation, requires two signals. Using the MUSIC algorithm)

计算DWT小波变换的JND值（恰可察觉性失真），用于图像水印的实现。以及DCT的水印实现(Calculate the DWT wavelet transform value of JND (Just Noticeable Distortion) for the image watermark. As well as the watermark of the DCT)

Hamming code. Simulation the BER to a code Hamming

说明：  本代码用来实现高光谱图像每个波段下灰度图像的保存，并且可将对应图像以相应的波段命名(This code is used to save gray image in each band of hyperspectral image, and the corresponding image can be named in the corresponding band.)
