Used function P(x) = 1+x− x2+0.2x3+0.1x4 and its known the values P(x)=[ -6.2 -8.3 -5.0 -1.1 1 1.3 2.2 8.5 27.4], in x= [-4 -3 -2 -1 0 1 2 3 4] to interpolate in the xi = − 4 + 0.1i, i = 0, 1, 2, . . . 80. Results are graphically compared!(Used function P(x) = 1+x− x2+0.2x3+0.1x4 and its known the values P(x)=[-6.2-8.3-5.0-1.1 1 1.3 2.2 8.5 27.4], in x= [-4-3-2-1 0 1 2 3 4] to interpolate in the xi = − 4+ 0.1i, i = 0, 1, 2, . . . 80.

说明：  这是书上的代码，C/C++中调用Matlab引擎的数值仿真的实现，供大家参考 (This is the code book, C/C++ Calling Matlab Engine Numerical Simulation for reference)

利用信息量原则定阶 用AR模型、x估计参数p(The principle of information for order with AR model, x estimated parameter p )

线性调频信号短时傅里叶变换 线性调频信号短时傅里叶变换 (chirp signal stft chirp signal stft chirp signal stft)

编写matlab程序，仿真2DPSK调制信号在高斯信道下分别采用相干解调及差分相干解调两种解调方式时的性能，并与理论分析结果相比较。(Write matlab procedures, simulation 2DPSK modulated signals in Gaussian channel performance respectively coherent demodulation and coherent demodulation difference when the two demodulation, and compared with the theoretical analysis.)

十种软件滤波.rar介绍了十种软件滤波的方法,不过我建议还是使用模拟滤波方法好.(10 kinds of filtering software. Rar introduction of dozens of software filtering method, but I suggest that the use of analog filtering methods or good.)

MATLAB code for generating faces using PCA. Displays all of the eigenfaces in a separate figure.

一本比较全面的关于matlab在数学建模方面应用的参考书，适合参加mcm和cumcm的同学。书比较清晰，源码可以直接复制！(matlab some of the basic algorithm!)

说明：  输出电压稳定不随输入电压、输出侧负载变化而变化，电流电压环pi参数已整定完毕，内外环配合良好。(The output voltage stability does not change with the input voltage and the load at the output side. The PI parameters of the current voltage loop have been set.)
