dct隐写技术matlab实现资料。算法原理：通过在一个图像块中调整两个DCT系数的相对大小，隐藏秘密信息。 将载体图像分为8×8的块，做二维DCT变换 用来表示选中的两个系数的坐标对于第i bit秘密信息 if（要隐藏信息‘1’） make else make 逆DCT变换，还原图像 (dct steganography matlab implementation information. Algorithm principle: an image block by adjusting the relative size of the two DCT coefficients, hidden secret information. The vector image is divided into 88 blocks, making two-dimensional DCT transform coefficients used to represent the coordinates of the selected two for the first i bit secret information if (to hide information ' 1 ' ) make else make the inverse DCT, restore image)

采用拉格朗日算法求解机组组合问题，采用的是5机系统(Lagrangian algorithm for solving unit commitment problem, machine system used is 5)

说明：  计算平面杆桁架结构动力特性，运动矢量迭代法和空间迭代法分别计算(Calculation of dynamic characteristics of flat-bar truss, and space motion vector iteration method iterative method were calculated)

基于matlba的常见信号设计，全部都经过实验验证，可作为子函数使用(Common Signal Design matlba based, all through experimental verification, use as Functions)

离散粒子群算法。粒子群算法原来只能处理连续变量，算法进行了改进，可以处理离散变量(Discrete particle swarm optimization algorithm, particle swarm optimization algorithm can only deal with continuous variables, the algorithm is improved, can handle discrete variables )

带端点延拓的EMD的matlab程序，可抑制端点效应(With the endpoint extension EMD Matlab procedures, can restrain end effect)

极大似然法，估算已知结点的位置，求出误差(Maximum likelihood method to estimate the location of known nodes, find the error)

Matlab实现NetworkCoding、reinform、SinglePath仿真(Matlab achieve NetworkCoding, reinform, SinglePath simulation)
