该资料包含目前热门的stm32的hal库学习资料(This information contains the current popular stan library learning materials for stm32.)

说明：  使用粒子群方法求函数的极值。里面一共两个.m文件，一个是函数表达式，一个是使用粒子群对这个函数表达式在有约束的条件下求极值的主函数(The extreme value of the function is obtained by using the particle swarm optimization method. There are two. M files, one is a function expression, and the other is the main function that USES the particle swarm to extremally evaluate this function expression under constrained conditions)

苏宁抢购 易语言实现 希望和大家交流交流(Suing snapped up...... exchange and exchange)

C#用子查询作表达式，查询学生表中指定科目的成绩超过其科目平均成绩的学生信息，一个结合数据库实现的程序，学习子查询的实现方法，如何使用子查询表达式。

读取4路mic的文件，然后经过gcc——phat处理，形成波束，然后加权之后写入文件。实测该算法降噪的效果还可以.另附一篇降噪文档，比较实用(Four mic files are read, then processed by GCC-PHAT to form a beam, and then written to the file after weighting.)
