标准粒子群算法，改进粒子群算法，希望大家能用上(Standard particle swarm optimization, improved particle swarm algorithm, hope everyone can be on the)

The MATLAB coding style, project options and synthesis directives can have a significant effect on the final results. Knowledge about how a particular algorithm should be implemented in hardware can be reflected in the MATLAB code to improve the results. In doing so, the MATLAB loses a bit of its abstraction but the lower-level MATLAB will infer the desired architecture into the device.(The MATLAB coding style, project options and synthesis directives can h ave a significant effect on the final results.

需要将音乐文件bhk_med.wav放于D盘根目录下才可以直接执行程序，或将程序中的音乐文件路径指向当前目的音乐所在的地址。背景音乐可以更换，甚至可以自行合成。(Music files need to be put in the D bhk_med.wav root directory before you can run the program directly, or to program the music file path to the address of the current purpose of music is located. Background music can be replaced, even on their own can be synthesized.)

lstm实例+代码，包含详细注释，能运行，简单的房产价格预测实例(Lstm u5B9E u4F9 u4E09 u4EF3 u643 U6D4B u5B9E u4F8B)

频率步进信号在雷达成像等需要大带宽的场景十分有用，该文件为国外经典文献，值得参考(Stepped frequency radar imaging signal in scenes that require large bandwidth is useful, the document for foreign classic literature, it is also useful)

用matlab编写的人工势场法路径规划算法演示程序，可以手动绘制障碍物，实现避障和对目标的跟踪，保证可以运行(Matlab prepared by the artificial potential field method of path planning algorithm demo application, you can manually draw obstacles, to realize the obstacle avoidance and target tracking, ensure that you can run)
