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

matlab关于对图形梯度的一般计算，很简单的一个小算法！-Matlab graphics gradient on the general terms, a very simple algorithm for a small!

多基时差雷达定位算法。以雷达测量误差分布规律入手，找到从多个地面时差雷达所测数据中找到较为精确的目标位置。对地面雷达的布站原则也有一定意义。-More than the time difference between the radar-based positioning algorithm. To the radar measurement error distribution to start to find the time difference from several ground-based radar measured data to find a more precise target location. Cloth on the ground radar stations have a certain sense principles.
