用LSB算法做图片隐藏，提取及检测，适合初学者学习参考(LSB algorithm to do image extraction and detection of hidden)

Matlab code computes 1.design of linear array 2. rectangular array 3.circular array 4.hexagonal array 5.array factor for an N-element uniformly spaced array.

Eigenface core matlab code

信道解码，适用于LTE下行接收端解码，一起系统仿真(Channel decoder for decoding LTE downlink reception side, together with the system simulation)

说明：  It is a matlab program for heat transfer modeling. The finite element is used.

0.618法求y=sin(x)在[0，2]极大值点(0.618 method y = sin (x) in [0, 2] the maximum points)

在这里，被控量是小车转角，向上回朔是舵机的转角，再向上就是用来控制舵机的PWM波的占空比，也就是说你的被控量是PWM波的占空比；一旦你的 舵机安装方式确定后，小车前轮的左右极限转角也就定死了，也就是说你的PWM波的占空比的变化范围也就确定了，即被控量的论域确定了，以我的为 例是1225到1725，显然S12的模糊机无法直接输出这么大的数值，在此对于输出量的隶属度函数我选用的是单值的，对应9个等级（0-8），即对应9个 PWM占空比值，即对应9个角度值。模糊语言等级、输出等级以及实际PWM占空比值的对应关系如下。 (Themohu function is used in mainly control applications. PIDCalc performs one iteration of the PID algorithm. While the PID function works, main is just a dummy program showing a typical usage.)

说明：  这是一个用matlab读取txt（特定格式）文件并读取文件，画出figure，自动保存和关闭figure。程序运用了深度搜索递归算法。（因为大家没有input的txt文件，所以阅读程序领会思想和方法即可）(This is a use matlab to read txt (a specific format) file and read documents, painted figure, on and off automatically to preserve figure. Procedures for the use of recursive depth search algorithm. (Because there are no input of the txt file, so reader can understand the ideas and methods))

说明：  本代码采用了adaboost算法进行仿真进行人脸检测，很好的给出了仿真图。(it uses adaboost to dtecte face. and it shows the pictures.)
