改进的虚拟激励法，用于大型结构的随机频域计算，在建筑、航天、机械领域已得到广泛的应用。(Improved pseudo-excitation method for the large-scale structure of random frequency-domain calculation, in the construction, aerospace, mechanical field has been widely used.)

自学MATLAB的良好教材，内含有该教材的源代码(Good self-teaching materials MATLAB, containing the source code of the material)

用matlab绘制光子晶体光纤的程序，可以绘制出六边形光子晶体光纤及其参数的设定(Draw photonic crystal fibers using matlab program, you can draw a set of hexagonal photonic crystal fiber and its parameters)

DOA 中的DML,DML为确定性最大似然算法，具有估计精度高、抗噪性强的优点(In DOA,DML is a deterministic maximum likelihood algorithm, which has the advantages of high estimation accuracy and strong anti-noise)

扰乱数据集函数，数据集采用 属性×实例数 格式存储，输出等同。(Disrupt the data collection function, the data set using the format attribute × number of instances stored in the output the same.)

Fixed-point for functions of several variables (Function fixed_point_systems(x0, N) approximates the solution of a system of nonlinear equations F(x) = (f1(x), f2(x), ..., fn(x)) = 0 rewritten in the fixed-point form x = G(x) = (g1(x), g2(x), ..., gn(x)). This is done by the user at the bottom of the file. The sub-function G(x) has to be updated accordingly with the given system. The iteration scheme x(k+1) = G(x(k)) is implemented until condition |x(k)- x(k-1)| < tol is met, starting with an initial approxiamtion vector x0. If, after N iterations, the stopping criterion is not reached, a message concerning the iterated x s is displayed. the output consists of iterates of each variables x1, x2, ..., xn in each column. )

说明：  EMDJ经验模态分解方法，可以直接进行使用(EMD decomposition method can be used directly)

测试文本，选用著名的gettysburg这篇英文文本做为测试文本(Second, it fuses the features of the first singular value component and the second one, and then gets the complex feature vectors which reflect not only the statistic frequency but also the sequential structure of letters. In the end, the cosine similarity of texts is used to measure the similarity between the query and documents.)
