Gaussian-filter

MATLAB的一本教材.很系统全面,可以作为学习提纲.(MATLAB in a textbook. A very systematic and comprehensive, can serve as a study outline.)

说明：  Function files in MATLAB for engineering constants for a lamina with a given arbitrary fiber orientation and given values of material data in the principal material directions.

汽车高斯曲面拟合 --- 2程序，以适应到表面二维高斯： 子= A *的进出口（ -（（西为X0）^2/2/sigmax^2 +（艺Y0的）^2/2/sigmay^ 2）。。）+ b的 这些例程是自动在某种意义上说，他们并不需要出发对模型参数的猜测规范。 autoGaussianSurfML（十一，彝，子）适合通过对模型参数的最大似然（最小二乘）。它首先计算了该模型在许多可能的参数值，然后选择最佳质量设置和细化与lsqcurvefit它。 autoGaussianSurfGS（十一，彝，紫）的估计，通过指定数据的贝叶斯生成模型，然后采取通过从模型吉布斯抽样样本后ofthis模型参数。这种(Auto Gaussian Surface fit --- 2 routines to fit a 2D Gaussian to a surface: zi = a*exp(-((xi-x0).^2/2/sigmax^2+ (yi-y0).^2/2/sigmay^2))+ b The routines are automatic in the sense that they do not require the specification of starting guesses for the model parameters. autoGaussianSurfML(xi,yi,zi) fits the model parameters through maximum likelihood(least-squares). It first evaluates the quality of the model at many possible values of the parameters then chooses the best set and refines it with lsqcurvefit. autoGaussianSurfGS(xi,yi,zi) estimates the model parameters by specifying a Bayesian generative model for the data, then taking samples from the posterior ofthis model through Gibbs sampling. This method is insensitive to local minimain posterior and gives meaningful error bars (Bayesian confidence intervals))

matlab中的cvx工具包,适用于windows64位系统，在信号的稀疏表示分类领域有很大的用处，网络上有此工具包的安装说明，1要先解压2移动到matlab的一个空文件夹下3打开matlab，将当前路径设置为此文件夹下的cvx文件夹4在命令行窗口输入cvx_setup(matlab in cvx toolkit for windows64 bit systems, in a sparse representation of the signal areas of the classification is very useful, this kit includes installation instructions on the network, first extract the 1 2 to move to an empty file folder under matlab 3 open matlab, the current path is set cvx file folders under this folder 4 in the command line window cvx_setup)

一种matlab实现的频率估计函数。matlab代码(A matlab function to achieve the frequency estimation. matlab code)

说明：  有关lfm的一些知识，希望对大家有一定的帮助(Some knowledge about FRFT transformation, we hope to have some help)

用lin法求高阶方程，可解特征方程, 可以是两队复根，可以是一对复根和两个实根，也可以是四个实根。(lin method, solve latent function)

On MATLAB in communication system application

The objective is to demonstrate character/ symbol frequency distribution analysis (reference to the English language) on 2 vintage ciphers, namely Caesar cipher (a mono-alphabetic substitution cipher) and the Vigenere cipher (a poly-alphabetic substitution cipher).

ADRC算法，根据韩京清的自抗扰技术慢慢看，含有王久和的交流电动机的非线性控制一起看(The ADRC algorithm, based on ADRC technology slowly to see Han Jingqing, nonlinear control with AC motor king long and together with the ADRC algorithm, based on ADRC technology slowly to see Han Jingqing, nonlinear control with AC motor and the king long together)
