Using logmap algorithm and maxlogmap algorithm with turbo codes.

分别设计理想低通滤波器、巴特沃思滤波器、指数滤波器、梯形低通滤波器,并对含高斯噪声的图像进行低通滤波，截止频率自选，观察不同的截止频率,不同的滤波器的滤波效果。(Were designed for the ideal low pass filter, Butterworth filter, exponential filter, ladder low-pass filter, and Gaussian noise images with low-pass filter cutoff frequency chosen to observe the different cut-off frequency, different filter filtering device.)

这个文件实现了Matlab/Simulink中的三维查找表，对要用到查表的人有帮助，里面用到Reshape函数(This file implements the Matlab/Simulink in a three-dimensional look-up table for use to help people look-up table, which used Reshape function)

Markov随机场的例子程序,对于初学MRF的人很有用,能得到直观的印象(Markov with airport procedures example, the MRF for a novice who was very useful, can be visual impression)

有限单元法求解一阶偏微分方程，使用的方法是加权余量法，比二阶方程更加可靠(Finite element method for second order partial differential equations, a method using a weighted residual method is more reliable than the first-order equation)
