本文用1961-2006年广西88个气象观测站的各月雨量资料，北半球500百帕月平均高度场资料(576个格点)，国家气候中心提供的部分环流特征量资料，通过EOF分解、合成分析、S(A practical estimate on the credibility formula is presented, where a piecewise linear function is taken as the approximation of the prior distribution and applied to the credibility theory. The convergence of the approximation is analyzed.)

空间平滑的MUSIC算法，适合学习，算法经典(Spatial smoothing MUSIC algorithm, suitable for learning classical algorithm)

一本电子TCL语言教程，可为学习OPENSEES提供方便，其他有两个为调用ABAQUS的源程序UVMAT，另外两个是求解动力问题的matlab程序(An electronic TCL language tutorials, can provide convenient for learning OPENSEES, there are two other for invoking UVMAT source of ABAQUS program, the other two is to solve the dynamic problem of the matlab program )

算法是原始对偶算法，该方法充分的剖析了优化问题的结构，是求解二次规划问题的一个较好的算法。求解比采用matlab 的Quardprog求解速度快许多！(Algorithm is the original dual algorithm, this method is fully analyzed the optimization of structure, is to solve the quadratic programming problem of a good algorithm. To solve the fast Quardprog than using matlab to solve many!)

仿真实现均匀圆阵任意阵元工作时的方向图，工作参数可任意调节(Simulation of uniform circular array of arbitrary array work pattern)

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.)
