去除脉冲噪声：中值滤波，均值滤波，PCNN滤波的比较，包括计算噪声图像的信噪比，matlab算法程序。(Remove impulse noise: median filter, mean filter, PCNN filter comparison, including the calculation of noise, the SNR, matlab algorithm program.)

说明：  用matlab写的印刷体数字识别程序，对matlab 6.0以上有效(Written with matlab print digital identification procedures, more effective on matlab 6.0)

This matlab code is used to reconstrcute 2D image by 2D_FFT.But we must resample the collected data by 2D interpolation.This method is useful and can be used in the real-time condition.

说明：  基于代码生成的28337磁悬浮双环pid控制(embedded code for 28377 based matlab)

it helps to enhance the ideas on wimax physical layer.

hi this is face tracking from multiple camera and enjoye u r life with u r friends

matlabb标准粒子群优化算法。 电力系统的分析和计算中，需要不同网络结构和参数。在应 用这些参数之前，收集和整理工作会花费大量的时间和精力。(matlabb standard particle swarm optimization. Power system analysis and calculation, require different network structures and parameters. Before applying these parameters, the collection and collation will spend a lot of time and effort.)

一道关于卫星导轨的数学建模代码；本人自己数学建模赛的源代码，共参加数学建模参考(A guide rail on the mathematical modeling of satellite code)

计算这一年已经逝去的天数（包括当天）。在平年中，它的取值范围为1到365，在闰年中，它的取值范围1到366。编写一个MATLAB程序，输入年，月，日，输出为对应的该天是当年的第几天。 闰年是这样规定的 1）.能被400整除的年为闰年 2）能被100整除但不能被400整除的年不为闰年 3）.能被4整除但不能被100整除年为闰年 4）.其余的年份不为闰年 (This year has calculated the number of days elapsed (including that day). In non-leap year, it ranges from 1 to 365 in a leap year, it s the range of 1 to 366. Write a MATLAB program, enter the year, month, day, corresponding to the output of the first year of the day is a few days. This leap is required 1) is divisible by 400 is a leap year 2) can be divisible by 100 but not divisible by 400 years is not a leap year 3) be divisible by 4 but not divisible by 100 is a leap year 4) the rest of the year is not leap year)

小波域理想濾波器，用了WACEREC2和RICE小波工具包兩種方法實現(wavelet ideal filter using waverec2 & rice wavelet toolbox)
