激光作为21世纪四大发明之一，在各个行业积极发挥着作用，这里介绍了各种常用激光器的参数和应用范围(Laser as a 21st century one of the four great inventions in various industries to actively play a role in a variety of commonly used lasers presented here the parameters and scope of application)

说明：  负载均衡调度问题：假设有N个任务，需要负载均衡器分配给M个服务器节点去处理。每个任务的任务长度、每台服务器节点（下面简称“节点”）的处理速度已知，请给出一种任务分配方式，使得所有任务的总处理时间最短。initRandomMat文件(Load balancing scheduling problem: suppose there are n tasks, which need to be allocated to m server nodes by load balancer. The task length of each task and the processing speed of each server node (hereinafter referred to as "node") are known. Please provide a task allocation method to minimize the total processing time of all tasks.initRandomMat)

fft变换仿真程序（应用于各种图像处理通信工程）(the code of frequency fft which can using in magic process and communication)

说明：  matlab程序设计。对初学者很有帮助，非常容易理解。(matlab programming. Very helpful for beginners, very easy to understand.)
