MImo detector , very useful for student

介绍一种有关卫星通信信号的快速盲检测方法(satellite communication signals quick blind detection)

说明：  可以快速实现从滞回曲线中计算耗能面积，和耗能系数，运行速度快，且稳定。(It can calculate the energy consumption area from the hysteretic curve quickly and stably.)

用matlab的小程序，希望对大家有所帮助！有限元结构动力学分析与工程应用. the code of <FEM ON DRYNIMIC analysys of enegineering >

说明：  matlab统计工具箱，概率分布举例应用，外加ode23运算举例(matlab learning)

Convert single precision IEEE hexadecimal string to number. By Matthias Nö ll.

there are 5 files. the first two codes are written in Matlab as m-files in control system design to show step responses. in contrast, the final three codes are written in verilog ( Quartus II) used in Altera one of them for BCD adder and the other for four to two bits encoder circuit.

说明：  蚂蚁所在的环境是一个虚拟的世界，其中有障碍物，有别的蚂蚁，还有信息素，信息素有两种，一种是找到食物的蚂蚁洒下的食物信息素，一种是找到窝的蚂蚁洒下的窝的信息素。每个蚂蚁都仅仅能感知它范围内的环境信息。环境以一定的速率让信息素消失。(The environment where ants are located is a virtual world, including obstacles, other ants, and pheromones. There are two kinds of information. One is food pheromone spilled by ants who find food, and the other is the pheromone of nest scattered by ants who find nest. Each ant can only perceive the environmental information in its scope. The environment makes pheromones disappear at a certain rate.)

说明：  function [ret,x0,str,ts,xts]=s3(t,x,u,flag) s3 is the M-file description of the SIMULINK system named s3. The block-diagram can be displayed by typing: s3. SYS=s3(T,X,U,FLAG) returns depending on FLAG certain system values given time point, T, current state vector, X, and input vector, U. FLAG is used to indicate the type of output to be returned in SYS.

在matlab系统中进行的kalman滤波器，并且在不同的参数情况下给出了比较(The kalman filter and comparsion with different fliters)
