googl earth 高程提取工具！对做google earth开发有一定的帮助！(googl earth elevation extraction tool! Google earth for doing development will certainly help!)

matlab滤波器,里面有三个方法滤波，用来滤波音频文件的(matlab filter, there are three ways to filter, for filtering the audio file)

使用吗matlab语言，实现很多模式识别上的经典算法，如PPerceptron_Batch算法等，已通过测试。 (Use the Matlab language, and many classic pattern recognition algorithm, such as PPerceptron_Batch algorithm has been tested.)
