1st FIR filter is given and wee need to find 2nd FIR filter that meet magnitude complementary criterion. fminsearch is used for error minimization.

sdemo.m为主文件，界面文件在subf文件夹，snake算法在snke文件夹下，images文件下为测试图片。 此程序以界面的方式展示了Snake算法的分割效果，如果需要做批处理，需要对其改进。(Sdemo. M primarily file, interface file in subf folder, snake algorithm in snke folder, images file for test under the picture. This program to the interface of the way to show the Snake algorithm of segmentation effect, if need to do a batch, needs to be improved.)

这几项M文件提供了扫描仪如何识别电子标签的方法，在许多场合都会涉及到这一类的智能识别。(This document provides a number of M scanner how to identify methods of electronic tag, in many occasions, will relate to this type of intelligent identification.)

说明：  基于最大似然估计的独立分量分析算法，包括随机梯度算法，相对梯度算法，快速不动点算法3个程序(Based on maximum likelihood estimation of independent component analysis algorithms, including stochastic gradient algorithm, the relative gradient algorithm, fast fixed-point algorithm for three programs)

说明：  线性调频信号在雷达上的实现，文中给出了设计过程，具有很好的参考价值(LFM radar signals the realization of paper gives the design process, with a very good reference value)

说明：  兰伯特投影变换，可将大地坐标与兰伯特坐标系左边相互转换(Lambert projection transformation)

一个很完整的LDPC程序，计算速度比较快,可实现多种速率的LDPC编码(a nice LDPC programm )
