matlab程序，1文件功能用FR共轭梯度法求解无约束问题，2、3文件分别表示目标函数和梯度(matlab program, a file function with FR conjugate gradient method for solving unconstrained problems, 2,3 document represent the objective function and gradient)

说明：  《MATLAB 7.0编程基础》第4章 （源码实例）主要讲解MATLAB的符号运算("MATLAB 7.0 programming foundation" Chapter 4 (source code examples) on the main website MATLAB No. Operational)

该代码采用matlab和C混合编写，是采用随机梯度的方法训练线性分类器，它可用于数据、图像等的多类分类情况。参考论文：Good Practice in Large-Scale Learning for Image Classification(This a Stochastic Gradient Descent algorithm used to train linear multiclass classifiers. It is biased towards large classification problems (many classes, many examples, high dimensional data).)

CoSaMP算法，在重构信号时，选取两倍稀疏度的原子来恢复原始信号，再删去一倍稀疏度的原子。(CoSaMP algorithm, in the reconstructed signal, select twice the atomic sparsity to recover the original signal, and then deleting the double sparsity of atoms.)

拥有VC界面的KALMAN滤波代码，仿真界面清晰易懂。(KALMAN filter with VC interface code, simulation interface clear and easy to understand.)
