利用matlab实现雷达信号分选仿真数据的生成，其中代码具有详细的解释，而且发之前已经测试是可以跑通的！！！

【实例简介】用java写的简易版购物车，大型网站很多都是这种模式，只是规模比这个大了很多倍，原理都是一样的，给大家分享一下，经国家免检，质量保证过关。

机器学习中的多种分类方法的matlab代码，程序正确可用，传上来一起分享交流。每个代码文件里面注释齐全，适合自学。

1，用的库是官方的HAL库2，硬件是原子的F429核心板（底板没有。。），用到的外设有，NANDFLASH、SDRAM、USB、一个按键3，播放设备用的是windows的ECap软件。4，NANDFLASH里面预存了原子的测试文件夹，里面有做好的AVI文件，名字是“[卢冠廷－一生所爱]_240160_10帧.avi”5，由于NANDFLASH读取速度不理想，变读取边发送USB的话，经常出错，而且帧卡顿，所以这里先把内容缓存到SDRAM上，然后在发送。6，使用方法是上电后，点击按键，开始缓存AVI文件到SDRAM中，大约1分钟左右，就可以在ECap上播放了7，可以在串口上看到一些打印
