针对DS-CDMA系统的QPSK调制方式的MATLAB仿真。(The simulation of QPSK modulation for DS-CDMA system based on MATLAB .)

在matlab，传统的边缘检测直接调用edge函数，但是得到的边缘信息较稀薄，可以通过将sobel,roberts,prewitt三种算子的边缘检测叠加起来，并且对于连续的边缘部分拓宽，使得边缘更连贯清晰(In matlab, traditional edge detection edge direct call function, but thinner than the edge information can be obtained by sobel, roberts, prewitt three edge detection operator stack up, and for widening the continuous edge portion, so that the edge is more consistent clear)

功能：用BFGS算法求解无约束问题：min f(x) 输入：x0是初始点，fun,gfun分别是目标函数及其梯度； varargin是输入可变参数变量，简单调用bfgs时可以忽略它， 但是其他程序循环调用时将会发挥重要作用 输出：x,val分别是近似最优点和最优值，k是迭代次数。(Function: BFGS algorithm for unconstrained problem: min f (x) Input: X0 is the initial point, fun, gfun each objective function and its gradient varargin variable parameter is the input variable, it can be ignored when a simple call bfgs , but other programs will play an important role when the cycle is called output: x, val are approximate optimum and the optimal value, k is the number of iterations.)

计算DGGE图谱各泳道间的相似性指数组成相似矩阵，输入参数x为图谱的泳道的亮度（灰度）或者比移值矩阵(DGGE profiles calculated similarity between each lane index composed of similar matrix, the input parameter x for the map of the lanes of the brightness (gray) or Rf value matrix)

本程序的性能已经超过其他算法，可实现对二维数据的聚类，是路径规划的实用方法，对HARQ系统的吞吐量分析，已调制信号计算其普相关密度，有CDF三角函数曲线/三维曲线图，采用波束成形技术的BER计算。(This program has exceeded the performance of other algorithms, Can realize the two-dimensional data clustering, Is a practical method of path planning, HARQ throughput analysis of the system, Modulated signals to calculate its density Pu-related, There CDF trigonometric curve/3D graphs, By applying the beam forming technology of BE.)

Matlab的Optimization软件包，虽然能很好地解决线性规划问题，但对于无解和有无穷个解地情况，结果不能让人满意，本人编了几个函数用于打印单纯形表。(Matlab Optimization package, Although able to solve linear programming problems, but no solution and a solution to the endless, the results are not satisfying. I compiled several functions for printing simplex table.)
