空时编码的一个matlab实现源程序，适合初学者。(Space-time coding to achieve a matlab source code, suitable for beginners.)

提出了一种基于小波变换可抗击几何攻击算法。在水印嵌人 部分# 首先对宿主图像进行小波分解 、 嵌人水印, 再通过余弦变换求得该水印图像的一个特征向量, 利用该特征向量和水印 信息通过12 31 函数生成一个二值逻辑系列, 将该序列作为密钥/ 水印提取部分为# 对待测的图像进行小波变换, 再通过余 弦变换求得待测图像的一个特征向量, 利用该特征向量和密钥通过1 2 4 1 函数提取出水印。(Proposed based on wavelet transform algorithm can be against geometric attacks.# Watermark embedded in the first part of the host image wavelet decomposition, embedded watermark, and then through the cosine transform of the watermarked image obtained by a feature vector, using the feature vector and the watermark information through 1231 to generate a binary logic function series, the sequence as the key/watermark extraction part is# treated transform measured image, and then obtained through the cosine transform the image of a feature vector under test, using the feature vector and the key function by 1241 to extract the watermark .)

MATLAB和maple语言均未直接提供求解fourier级数的系数的直接函数，自己动手丰衣足食，下面提供了一个代码，大家可以参照下 (MATLAB language, and maple were not directly solve the fourier series coefficients of the direct function, it-yourself ample food and clothing, the following provides a code, we can refer to the next)

自己编的一个用随机行走法实现电路计算的例子，电路图及参数均在Partial random walk for large linear network analysis里(Own a random walk method used to achieve circuit examples, circuit diagrams and parameters in the Partial random walk for large linear network analysis in)
