根据伊忠科、杨绍国（电子科技大学）发表的论文"分形插值图象放大和压缩编码"编程实现。(Branch, Shao- Guo Yang (University of Electronic Science and Technology) by the paper, "Fractal Image interpolation and compression coding Large" program.)

学习信道建模的经典教材！尤其是对无线信道建模空时频特性进行仿真的一部重要书籍。(A classic learning textbook about wireless channel modeling!Especially it s an important book for the time-space and frequency characteristics of wireless channel modeling simulation .)

说明：  快速迭代收缩阈值算法，FISTA用一种更为聪明的办法选择序列{xk}，使得其基于梯度下降思想的迭代过程更加快速地趋近问题函数F(x)的最小值。FISTA的缺点是：Lipschitz常数L(f)不一定可知或者可计算。(Fast iterative contraction threshold algorithm, FISTA uses a more clever method to select the sequence{xk}, making its iterative process based on the gradient descent idea more quickly approach the minimum value of the problem function F(X). The disadvantage of FISTA is that the Lipschitz constant L(f) is not necessarily known or computable.)

pso的matlab已通过编译运行的源程序代码(pso source code)

说明：  最小二乘支持向量机的matlab工具箱，包含几乎所有常用的支持向量机应用函数。(Least squares support vector machines matlab toolbox, including almost all commonly used applications of support vector machine function.)

这是中国数学建模中编程交流上贪婪算法内容，里面提供了很多贪婪算法的例子(This is the exchange of mathematical modeling in the programming content on the greedy algorithm, which provides many examples of greedy algorithm)
