非线性MPC问题求解,简单但是基本的例子(to solve the NMPC problem)

xwch_test.m是主测试文件；biaoji.mat存放滤波器系数；xiangweicha.m用FFT计算相位差。 仿真框架为： 1.标记信号和双音信号续接作为发送信号； 2.对双音中一个频率分量的相位做偏移，再经过一个低通滤波器（引入线性相位，模拟收发不能同步测量现象）后，作为收到的信号； 3.用一个检测信号对收发信号进行相关运算； 4.画出收发信号以及相关处理后的信号。找出相关信号的那个尖点，从而推算出收发双音信号0相位点； 5. 输入0相位点位置，计算相对相位差。(xwch_test.m is the main test file biaoji.mat store filter coefficients xiangweicha.m calculated using FFT phase difference. Simulation framework: 1. Mark signals and then as a two-tone signal continued to send signals 2. On a two-tone frequency components of the phase shift to do, and then through a low pass filter (the introduction of linear phase, simulation can not simultaneously send and receive measuring the phenomenon), the as received signal 3. using a detection signal of the transceiver signal correlation operation 4. draw send and receive signals and related processed signal. Correlated signal of the cusp, which calculate the two-tone signal transceiver 0 phase point 5. Enter 0 phase point position, calculate the relative phase difference.)

说明：  使用matlab工具进行边缘检测，基于小波多尺度变换。(Matlab tools use edge detection, based on wavelet multi-scale transform.)

此代码为图像处理技术中的沃尔什-哈达玛变换，实现图像的压缩处理(This code is an image processing technology Walsh- Hadamard transform, image compression)

数值计算-插值【matlab例程】经典算法直接应用方便快捷(Numerical calculation- interpolation routines] [classical algorithm matlab convenient direct application)

说明：  该算法非常适用于正系统、正切换系统等仿真(NUMERICAL SIMULATION FOR POSITIVE SYSTEMS and positive switched system)

线性分类器-最小平方误差算法，对一组数据进行分类，分析b1、b2改变对结果的影响(Linear classifier- the least square error algorithm)
