high boost filter in matlab

通过差值方法填补matlab变量中的NAN值，针对二维以内的变量，变量中不能有整行或整列的NAN值(Fill NAN value in matlab variables by the difference method, for less than two-dimensional variables, variables can not have an entire row or column values ​ ​ of NAN)

用于cml860芯片收发DTMF和FSK信号(Cml860 for DTMF and FSK transceiver chip signal)

MATLAB源码，preprocessing.m: preprocess the picture including:Wiener filter; meddle value filter, change a gray picture to a binary one and then get the skeleton. centralizing.m: input the source picture output the core point of the fingerprint. samfun.m: generate the sample pattern automatically, which is used to sample the fingerprint. gabor2d_sub: get gabor filter. varpic.m: calculate variance picture(MATLAB source, preprocessing.m : preprocess the picture including : Wiener filter; meddle value filter, change a gray picture to a binary one and then get the skeleton. centralizing.m : input the source picture output the core point o f the fingerprint. samfun.m : generate the sample pattern automatically, which is used to sample the fingerprint. gabor2 d_sub : get gabor filter. varpic.m : calculate variance picture)

减采样实例 增采样实例 线性插值实例 改变采样率实例(Reduce the sampling instance By sampling instance Linear interpolation examples Instance of changing the sampling rate)

说明：  智能控制matlab仿真源程序，实现智能控制算法(Matlab simulation intelligent control source, the realization of intelligent control algorithm)

3d reconstruction based glass cubes

选择输入信号的参数，以及抽样因子，以及采样参数，对信号分别进行上抽样和下抽样，方便非均匀采样的进行。(Select the input signal parameters, and sampling factors, as well as sampling parameters, respectively, on the signal sampling and down sampling, to facilitate the conduct of non-uniform sampling.)

This funtions draw circles to the limbic and pupillary boundary. this function is used in the daugman algorithm after the steps of thresholding and partial differeniation.

线性方程直接解法的matlab程序，可作为数值分析等的学习工具。(The direct solution of linear equations matlab program, can be used as numerical analysis , and other learning tools.)
