A fast Fourier transform (FFT) is an algorithm to compute the discrete Fourier transform (DFT) and its inverse. Fourier analysis converts time (or space) to frequency and vice versa an FFT rapidly computes such transformations by factorizing the DFT matrix into a product of sparse (mostly zero) factors.

复杂网络，系统设计，牵制控制，可自行设计控制点、网络节点。内耦合矩阵，外耦合矩阵，采用全局网络，实现分析系统是否收敛。可求平衡点，Jacabi矩阵等等(Complex networks, systems design, contain control, can design their own control point, the network node. Coupling matrix within and outside the coupling matrix, using the global network, analysis of the system is to achieve convergence. Rectifiable balance, Jacabi matrix, etc. )

综述了光纤光栅传感器近年来在工程结构健康监测、石油产业、电力行业、岩土工程、航空航天、采矿、爆破、交通及 医学等各个领域的应用情况。文章认为，限制光纤光栅传感器产业化和大规模应用的主要因素是缺乏统一的设计理论 和制作方法，这使得不同厂家生产的传感器规格存在差异。另外，由于复杂的生产技术和精细的生产过程使传感器生产 成本较高，而且能实际应用的光纤光栅传感器的解调产品并不多，且价格很高。根据上述分析，文中对该项技术未来的 发展方向提出了展望。(Overview of FBG sensors in recent years in various fields of engineering structural health monitoring, oil industry, power industry, geotechnical engineering, aerospace, mining, blasting, transportation and medical and other applications. Article that the main factor limiting FBG sensors and large-scale industrial applications is the lack of a unified design theory and production methods, which makes the sensors from different manufacturers specifications differ. In addition, due to the complexity of the production technology and sophisticated production process so that the sensor higher production costs, but also the practical application of fiber grating sensor product is not much, and the price is very high. Based on the above analysis, the article on the future direction of the technology raised the prospect.)

用改进pso求解贷款方面程序，希望能对大家有帮组(Pso solved by improved lending procedures in the hope we have helped groups can)

To find a triangulation of minimal total edge length. That is, an input polygon or the convex hull of an input point set must be subdivided into triangles that meet edge-to-edge and vertex-to-vertex, in such a way as to minimize the sum of the perimeters of the triangles.
