THIS CODE IS REG.IMAGE STEGNOGRAPHY

对测量专业中不同时期观测的数据进行精度是否相同进行统计检验(The measurement data of observation in different periods in the professional statistical test accuracy are the same )

These are MATLAB codes for implementing Chebyshev-Type 2 Bandpass and Bandstop filters.

说明：  looking the nearest distance

说明：  蒙特卡洛求pi，非常简单的求pi值的代码源(Monte Carlo for pi, a very simple code for the source of the value of pi)

Identify tables and interactively select the data to bring into MATLAB

卡尔曼滤波器的Simulink仿真，完全可以实用！(Kalman filter Simulink simulation, can be useful!)

SVM方法的基本思想是：定义最优线性超平面，并把寻找最优线性超平面的算法归结为求解一个凸规划问题。进而基于Mercer核展开定理，通过非线性映射φ，把样本空间映射到一个高维乃至于无穷维的特征空间（Hilbert空间），使在特征空间中可以应用线性学习机的方法解决样本空间中的高度非线性分类和回归等问题。svm 程序，即支持向量机的代码。(The basic idea of SVM method are: the definition of the optimal linear hyperplane, and the search algorithm for optimal linear hyperplane by solving a convex programming problem. Then based on Mercer nuclear expansion theorem, through a nonlinear mapping φ, the sample space is mapped to a high-dimensional and even infinite dimensional feature space (Hilbert space), so that in the feature space can be applied to solve the linear learning machine method, the sample space The highly nonlinear classification and regression problems. svm procedures that support vector machine code.)
