代码说明:

应用背景将函数f(x)近似的表达为:   叫作函数的pade近似,Matlab中没有直接提供相关函数, 关键技术但是我们可以根据原理,比较容易的写出Matlab代码: 比如需要将f(x)=exp(-2*x)展开成有理多项式,进行pade近似,根据下面提供的padefcn()函数,我们可以轻松的实现

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

  • CSP 代码共同的空间分布格局
    对于脑电信号(EEG)特征提取的问题,因为 EEG 信号非常微弱(微伏级),甚至噪声的强度会超过有效的 EEG 信号,因此使得特征提取问题变得困难。目前应用广泛的一种方法是共同空间模式(Common spatial pattern,CSP)算法,该算法已经在一些 BCI 应用中显示出较好的特征提取性能。

  • JPHide 和JPSeek 的源代码
    应用背景JPHide 和JPSeek 的源代码!JPHide&JPSeek是一个JPEG图像的信息隐藏软件!-JPHide and JPSeek source code! JPHide & JPSeek is a JPEG image information hidden software!关键技术JPHIDE and JPSEEK are programs which allow you to hide a file in a jpeg visual image. There are lots of versions of similar programs available on the internet but JPHIDE and JPSEEK are rather special. The design objective was not simply to hide a file but rather to do this in such a way that it is impossible to prove that the host file contains a hidden file. Given a typical visual image, a low insertion rate (under 5%) and the absence of the original file, it is not possible to conclude with any worthwhile certainty that the host file contains inserted data. As the insertion percentage increases the statistical nature of the jpeg coefficients differs from "normal" to the extent that it raises suspicion. Above 15% the e
