要用灰色模型预测2020年人口数，请赐教(In the gray prediction model to the population in 2020 ..)

说明：  实现大容量的图像信息隐藏，采用双随机置乱算法(Realize large-capacity image information hiding, using double-random scrambling algorithm)

matlab的龙贝格算法，简单便捷，可以来下载哦(Romberg algorithm in matlab , simple and convenient , you can download )

基于时延估计的目标定位与跟踪：编写了一个Matlab GUI，可以实现三围空间目标的定位，以及运动目标的跟踪(The Target_Positioning_&_Tracking Through Time-Delay-Estimation.)

denoising filters such as Average, Median, Gaussian, Wiener, Min-order-statistic, Maxorder-statistic and Median-order-statistic are used. Based on the images obtained by the mentioned filters, it is become obvious clear that for the given noisy image the Min filter acted much better than the other filters. Order-statistic Median and Gaussian filters are the ones that have a second and third good result respectively. That is way can conclude that the existing noise in the given image was Salt noise.

说明：  该程序的功能是将matlab的mat文件转化成labview中的波形文件，便于在labview中应用mat文件里的数据。(it can change the mat file to vi file which is used in labview.)

在matlab环境下实现了对MPSK通信系统的仿真，(mpsk)

律u律pcm编码 若输入A律PCM编码器的正弦信号为x(t)=sin(1600πt),采样序列为x(n)=sin(0.2πn),n=0,1,2,…,10，将其进行PCM编码，求出编码器的输出码组序列y(n)。 要求：1) 直接采用A律扩展器函数求解上述问题。 2）使用13折线法近似A律PCM 求解上述问题。 3）计算量化误差。(Law a law pcm coding If the input A-law PCM encoder is sinusoidal signal x (t) = sin (1600πt), for the sample sequence x (n) = sin (0.2πn), n = 0,1,2, ..., 10, it will be PCM coding to obtain the coded output code group sequence y (n). Requirements: 1) directly A-law expander function to solve the above problems. 2) using a 13 fold line approximation A-law PCM to solve the above problems. 3) calculating the quantization error.)
