无限长的序列也往往可以用有限长序列来逼近。对于有限长的序列我们可以使用离散傅立叶变换（DFT）。DFT是对序列傅立叶变换的等距采样。是序列傅立叶变换的等距采样。 本源码是对DCT、DFT、FFT的matlab实现(Infinitely long sequence is often a long sequence with limited approximation. For the finite length of the sequence we can use the discrete Fourier transform (DFT). DFT is a sequence of equidistant sampling Fourier transform. Is a sequence of equidistant sampling Fourier transform. The source is the DCT, DFT, FFT in matlab implementation)

Fast search for Dirichlet process mixture models (This code implements the search algorithms (modulo a few minor changes) described in the Fast search for DPMMs paper at AI-Stats 2007. It should work out of the box with a reasonably recent version of matlab. Currently the code only contains the Dirichlet/Multinomial case, but the Gaussian case can be hacked in in about 5 minutes.)

用SURF实现图相配准，可以自行修改图片！！(SURF Image registration)

控制问题转化为了数学规划问题。推导出目标函数对于待求参数的梯度公式，并利用序列二次规划算法求出最优控制量(the problem is changed into mathematical programming problem and formulae are derived for computing the gradients, also, a computational method for finding the optimal control is obtained by using the Sequential Quadratic Programming (SQP) algorithm.)
