说明：  用于模拟光纤中的非线性薛定谔方程，包含了色散、非线性等现象的模拟，对与想了解脉冲在光纤中的传输变化非常有帮助(Used to simulate the optical fiber in the nonlinear Schr&ouml dinger equation, including the dispersion, nonlinear phenomena such as analog, pulse on and want to understand changes in the transmission fiber is very helpful)

it is a matlab code for doing a poincare section to reduce a flows dimension and making a map

matlab中值滤波源代码，对于图像处理的人员有一定的参考意义。。(median filter matlab source code for image processing personnel have some reference value. .)

We first present the Hypothesis Selection Filter in a general setting. For a given image enhancement problem, suppose we have selected a set of image filters each of which is effective in improving the image quality for a certain type of content. Our objective is to combine the filter outputs to obtain an overall best quality result. In the following, we use upper-case letters to denote random variables and random vectors, and lower-case letters to denote their realizations.
