非常有用的nonlinearDBR程序，研究光栅的快点下哈！！(Very useful nonlinearDBR processes to quickly grating under Ha! !)

used to filter the latent state variable

12元均匀线列阵，DFT波束形成 功能：阵元间隔为对应于频率f0的半波长。假设一线性调频信号源从-30°方向入射到 基阵，不考虑噪声，进行DFT波束形成。(12 yuan uniform linear array, DFT beamforming Function: array element spacing corresponding to half the wavelength of the frequency f0. Suppose a linear FM signal source is incident the direction of-30 to the base array, without regard to noise, performs DFT beamforming.)

说明：  提取LPC参数进行，倒谱系数的计算，用于静音检测算法，(Extract LPC parameters, the calculation of cepstral coefficients for mute detection algorithm)

八阵元智能天线阵列接收4个信号，用Matlab仿真实验验证波达方向估计，主要涉及的算法是MUSIC和MVDR(Eight smart antenna array receiver array element 4 signals, with the Matlab simulation results verify the estimation, mainly related to the algorithm is MUSIC and MVDR)

图像配准程序研究，这是我自己编写的一个代码。如有不足，请多多包涵！(tuxiangpeizhunchengxu，zijixiede)

用3中误差扩散滤波器实现误差扩散，分别是floyd stein, sierra, Stenenson滤波器(Error diffusion filter with a 3 to achieve error diffusion, respectively, floyd stein, sierra, Stenenson filter)

说明：  MATLAB提供了多种方式从磁盘读入文件或将数据输入到工作空间，即读取数据，又叫导入数据；将工作空间的变量存储到磁盘文件中称为存写数据，又叫导出数据。(MATLAB provides a variety of ways from the disk is read into a document or data entered into the work space, that is, read data, also known as import data will work variable storage space to keep the disk file is called to write data, also known as export data .)

Gridding is a method of interpolating data from an arbitrary 2D sampling pattern to a uniform grid. In MRI, this allows rapid image reconstruction. There are numerous publications on MR gridding reconstruction. The tar file includes numerous .m scripts, and C code that can be compiled to a .mex function. You will need to compile the MEX functions - in Matlab try "mex gridlut_mex.c" and "mex calcdcflut_mex.c" These should result in files gridlut_mex.mex??? and calcdcflut_mex.mex??? where ??? depends on your operating system. Run the function spiralexample.m in Matlab. (Gridding is a method of interpolating data from an arbitrary 2D sampling pattern to a uniform grid. In MRI, this allows rapid image reconstruction.

拉丁超立方体抽样，是一种初始化常用的方法，使得种群初始化更均匀(Latin hypercube sampling is a common method of initialization, which makes the population initialization more uniform)
