求解无约束最小化问题的牛顿方法 matlab程序(Solving Unconstrained Minimization problem with Newton method (matlab))

说明：  《现代通信系统使用MATLAB（第二版）》书中的例子打包。(communication systerm)

基于MATLAB的OFDM仿真程序，仿真模块包括BPSK,QPSK,16QAM,64QAM(MATLAB simulation program based on the OFDM simulation module including BPSK, QPSK, 16QAM, 64QAM)

该压缩文件为污水处理系统的建模、诊断和控制的全部程序和说明，非常实用。(The compressed file sewage treatment system modeling, diagnosis and control of all procedures and instructions, very practical.)

用matlab编写的在png图像中隐藏并提取rgb图像和二值图像，注意隐藏的图像要小点，源图像png要大些(Png images using matlab hide and extract the rgb image and binary image, pay attention to the hidden image is smaller point source image png)

说明：  抛物线法求解 方程的构造方法:给出[0,1]区间上的随机数(服从均匀分布)作为方程的根p*. 设你的班级数为a3,学号的后两位数分别为a2与a1,从而得到你的三次方程 例如:你的31班的12号,则你的方程是21x3+60x2+2x+a0=0的形式. 方程中的系数a0由你得到的根p*来确定. (parabolic equation method Construction Methods : given interval [0,1] on the random number (subject to uniform distribution) as the root equation p*. set up your classes at a3, after learning of the double-digit for a1 and a2, so you get the three equations for example : your 31 classes on the 12th, then your equation is 21x3 60x2 2x a0 = 0 forms. the equation coefficients a0 you get from the root of p* to determine.)

说明：  同样是用matlab编写的实现支持向量机的源代码(using Matlab is also prepared to achieve SVM source code)
