W elcome to X CELL, the new Xilinx customer newsletter. By sending us your development system registration card you automatically became n charter subscriber to this quarterly publication. It is our intent to make this an informative, easy to read, responsive and-hopefully- interactive newsletter. We want to supply you with early and correct information, tell you about the status of our products and about our plans, about bugs and their workarounds, give you applications ideas and convey to you some of the en thusiasm that we feel for our Programmable Gate Arrays. If you have questions or suggestions, please send them to me. II Letters to the Editor make a newsletter more lively. Peter Alfke, Editor

说明：  用粒子群算法解决背包问题，能得到比较有效的结果(Particle swarm algorithm to solve knapsack problem, the results can be more effective)

本教程提供了使用MATLAB的实践性指导，它基于MATLAB6.0版，内容由浅入深，特别是本书对每一条命令的使用格式都作了详细而又简单明了的说明，并配备了例题加以说明其用法，因此，对于初学者自学是很有帮助的；同时，又对数学中的一些深入问题如数值分析、稀疏矩阵、优化理论以及模糊数学等问题进行了较为详细的论述，因此，该书也可作为科技工作者的科学计算工具书。(practical guide for matlab users)

银表面等离子激元SPP色散关系，参考王振林老师的《表面等离子激元的研究进展》(Silver surface plasmon dispersion relation of SPP, reference Zhenlin teacher " Surface plasmon Research Progress" )

利用卫星水色数据进行可视化，包括对图像的修饰和处理，数据插值。(Use of satellite ocean color data visualization, including image retouching and processing, data interpolation.)

通过pch文件提取nastran质量矩阵、刚度矩阵，需要更改文件名称和自由度数（dof）,生成质量矩阵、刚度矩阵M,K(Extraction of mass matrix, stiffness matrix of NASTRAN)

在matlab里自行用简单语句编写的卷积运算程序，一道小作业题。(In matlab in their own written statement with the simple convolution procedure, a small job title.)

说明：  卡尔曼滤波实验和卡尔曼时间预测 包括从gps数据中读取经纬度(Time Kalman filter and Kalman prediction experiments, including data read from the gps latitude and longitude)

OFDM多载波调制方式的DFT变换，以及OFDM波形的仿真(OFDM multi-carrier modulation of the DFT transform, and the OFDM waveform simulation)

独立成分分析的算法FastICA法（也叫固定点算法）(Independent component analysis algorithm FastICA method (also called fixed-point arithmetic))
