ＴＥ波和TM波照射到二维导体柱上带你电流分布，各个方向的RCS以及总的ＲＣＳ随导体尺寸的变化(TE wave and TM wave illumination column take you to the two-dimensional conductor current distribution, in all directions of the RCS and the RCS with the total change of conductor size)

说明：  本程序采用迎风方案实现推广GAC模型的水平集方法，用于图像处理，具有较好的效果(The program uses the wind to promote the program to achieve the level set method GAC model for image processing, with good results)

自己做的一个ns－2下的flood仿真程序演示结果(a flood protol for wsn in ns2 simulator.)

DEMODULATOR: This function performs demodulation of the forward Channel packet, based on RAKE Receiver Block Diagram Input Signal -> [Matched Filter] -> [Sampler] -> [RAKE Receiver] -> [Walsh] -> [DeSpreading] Inputs: RxIn - input signal (I/Q) analoge PN - PN sequence (used for De-spreading) MF - matched filter taps Walsh - Used row of Walsh matrix for recovering

说明：  现在手头有一个matlab程序，是关于如何改变坐标轴范围的。跟大家分享下！(change the range of the axis)

Given signal-to-noise ratio and bit error rate performance curve is a good beginner s reference program.

基于matlab编写了SQP法，乘子法，共轭梯度法，拟牛顿法，信赖域法，最速下降法与牛顿法的最新程序，功能很强大，可供编程参考。(Based on the preparation of MATLAB SQP, multiplier method, conjugate gradient method, quasi-Newton method, trust region method, steepest descent method with the Newton-Raphson method the latest procedures, functions very powerful, can be used for programming reference.)
