WGS-84 -> ECEF ECEF -> WGS-84 极坐标系 -> ECEF ECEF -> 极坐标系(WGS-84-> ECEF ECEF-> WGS-84 polar-> ECEF ECEF-> polar)

Application of rule d nearest neighbor to build the partition of the Vornoi

给出了数字信号处理课程设计的基本程序，包括采样、快速傅里叶变换、功率谱分析等。(Give a digital signal processing of the basic procedures for curriculum design, including sampling, fast Fourier transform, power spectrum analysis.)

说明：  该软件和代码实现的功能是对图象的加密和解密,运行环境是Xp+matlab,代码中有说明,很容易看明白.(the software code and the functions of the image of encryption and decryption, the environment is Xp Matlab, the code is described, it is easy to see to understand.)

实现ID3算法，在结果中以树表示出来。决策树是对数据进行分类，以此达到预测的目的。该决策树方法先根据训练集数据形成决策树，如果该树不能对所有对象给出正确的分类，那么选择一些例外加入到训练集数据中，重复该过程一直到形成正确的决策集。(ID3 algorithm to achieve, in the results that come out to the tree. Decision tree is to classify the data, thus achieving the purpose of prediction. The decision tree training set of data according to the formation of the first decision tree, if the tree can not give the correct classification of all objects, then select a number of exceptions to the training set data, repeat the process until the correct decision set.)
