compute a ROC curve hope you will like it

一种基于chan算法的tdoa定定位的gdop程序源码 (Given the positioning gdop program source code algorithm TDOA based chan)

说明：  地震资料的谱分解的matlab的程序，需要的可以直接带走(Seismic data, spectral decomposition matlab procedures, need to be taken directly)

实现了DQPSK下用Gardner算法实现位同步，并对信噪比、余弦滚降因子的影响加以讨论(achieve symbol synchronous by Gardner in the condition of DQPSK)

这是matlab的一个入门教程，结合实例介绍了matlab在数学中的应用。(This is a Getting Started tutorial matlab, matlab introduced with examples of applications in mathematics.)

说明：  matlab编程，实现了基于内容的图像检索，基于颜色直方图和边缘直方图(Matlab programming, achieve a content-based image retrieval, based on the color histogram and the marginal histogram)

对于已经给定的特征，能够运用神经网络强大的处理复杂数据稳定的能力，给予有效的分类，达到很好的识别效果。(Has been given the characteristics of the use of powerful neural network to handle complex data and stable capacity to give a valid classification, to achieve good recognition results.)

基于扩频的数字水印技术，水印信息分布于载体作品的多个频率系数，每个频率系数上负荷的水印能量很小，平衡水印的鲁棒性和不可感知性上的矛盾。(Digital watermarking based on spread spectrum technology, the watermark is found in a number of frequency coefficient vector works, each frequency coefficient on the load of the watermark energy is small, balance the robustness and non-perception of the conflict.)
