sin and cosine of atan(y/x) [S,C,R,T]=(Y,X)

对企业到金融商业机构贷款，金融商业机构需要对企业进行评估(To the financial and commercial institutions of corporate loans, financial and commercial institutions to assess the need for enterprise)

调制:对每个空间流分别进行调制，输入分别为每个空间流的所有6760列、调制类型，输出结果为2行3380列复数。(Modulation: separately for each spatial stream are modulated, respectively, for all the input 6760 of each of the spatial streams, modulation type, the output of the second row 3380 complex.)

The function takes at least three input arguments (function, its derivative, and an initial guess). After iterations, it gives the root of the function. The fourth input argument is to change the stopping criteria.

Matlab基础及其应用教程，提供给matlab初学者，很好的教材(Matlab and its application tutorial, available to matlab for beginners, good textbooks)

数据模型归一化，模态振动，模拟数据分析处理的过程，人脸识别中的光照处理方法，包括最小二乘法、SVM、神经网络、1_k近邻法,Pisarenko谐波分解算法,电力系统暂态稳定程序，可以进行暂态稳定计算。

想保留的成分为cos(2*π*n/3) 带通滤波器，滤除1+cos(2*π*n/3) 的成分，即想保留的成分为cos(π*n/4) 带阻滤波器，滤除cos(π*n/4) 的成分，(Want to keep the ingredients for the cos (2* π* n/3) band-pass filter, filter 1+ Cos (2* π* n/3) of the composition, that is, want to keep the ingredients of cos (π* n/4 ) band-stop filter, filter cos (π* n/4) of the composition,)

说明：  继续上次传的简单遗传算法，本次加入啦测试部分。(Continue to the last mass of the simple genetic algorithm, to join you in this part of the test.)

最后的测试程序，得出文本检索的正确率和召回率(In the end, the cosine similarity of texts is used to measure the similarity between the query and documents. The data comparison indicates that this algorithm has well experimental results. Moreover, it gets the advantage over the classic LSA retrieval algorithm in precision and operational efficiency.)
