基于遗传算法优化支持向量分类机参数的matlab语言编码(Support vector machine optimized by genetic algorithm)

计算七类窗函数并给出归一化对数幅频曲线,同时也是利用窗函数法设计FIR滤波器的程序MDEFIR1所调用的子程序MWINDO(Seven kinds of window functions are calculated and normalized logarithmic amplitude-frequency curves are given. At the same time, it is also the subroutine MWINDO called by the program MDEFIR1 of designing FIR filter by using window function method.)

Hadoop 的运行方式是由配置文件决定的（运行 Hadoop 时会读取配置文件），此外，伪分布式虽然只需要配置 fs.defaultFS 和 dfs.replication 就可以运行（官方教程如此）。(The mode of running Hadoop is determined by the configuration file (the configuration file is read when running Hadoop). In addition, the pseudo distributed can run only by configuring fs.defaultFS and dfs.replication (the official tutorial is the case).)
