程序计算并画出1D和2D阵列。由Designed by Mohamed H. Awida Ain Shams University, Faculty of Engineering, Electronics and Communication Dep.Egypt.设计 (The program computes and plots the array factor of 1D and 2D array .Designed by Mohamed H. Awida Ain Shams University, Faculty of Engineering, Electronics and Communication Dep. Egypt. )

说明：  对信号类型的说明，并画出其相应的波形，求出信号的功率和能量。(Description of the type of signal, and draw the corresponding waveform, find the power and energy of the signal.)

Euler-maruyama 方法生成色噪声(Euler-maruyama method to generate colored noise)

MPI Config message, structures, and Pages.

一个对数据处理的Matlab函数，统计数据的概率分布并画出概率密度曲线，已经验证，将该函数安装在函数工具箱内即可调用。(A data processing of Matlab function, the probability distribution of the statistical data and draw the probability density curve, have tested, the function will be installed in the tool can function call. )

PSNR峰值信噪比在两个图像上的比较。此程序为一函数。(PSNR comparison of the two images)

余弦波是渐变的，当ωt+φ的取值变化量很小时，Y的变化量也是很微小的。余弦波的这一特性保证了嵌入水印后相邻字符灰度值差别不大，人眼无法识别，从而保证了水印的不可见性和图像质量。(Cosine wave is gradual, and when ωt+ φ values variation is very small, Y amount of change is very small. Cosine waves This feature ensures that watermarked gray value of adjacent character is not very different, the human eye does not recognize, thus ensuring the invisibility of watermark and image quality.)

用于改进的wilson叶片设计，亲测可行。(wilson design for wind blade)

说明：  ar模型预测，通过yule方法得到了ar系数，然后对一组随机数进行了预测。(The ar model predicts, through the yule methods ar coefficient predicted, then a set of random numbers.)

SIFT特征（Scale-invariant feature transform，尺度不变特征转换)是一种电脑视觉的算法用来侦测与描述影像中的局部性特征，它在空间尺度中寻找极值点，并提取出其位置、尺度、旋转不变量(SIFT features (Scale-invariant feature transform, scale-invariant feature transform) is a computer vision algorithm to detect and describe the image characteristics of the locality, it scales in space to find extreme points, and extract its location , scale, rotation invariant)
