是对巴特沃斯滤波器设计的详细讲述，对于初学者有很好的帮助。我觉得比较实用。(Butterworth filter design is described in detail for the beginners have a good help. I think the more practical.)

matlab 实用程序百例,介绍matlab函数库,图象处理中的通用程序.(100 cases of matlab utility, introduction matlab function library, image processing procedures in general.)

说明：  乘积的最后三位的值只与乘数和被乘数的后三位有关，与乘数和被乘数的高位无关，利用此来求尾数(The last three values of the product only with the multiplier and the multiplicand on the back three, with a high multiplier and the multiplicand has nothing to do, take advantage of this to seek mantissa)

说明：  是个好东西，给大家共享了，希望对大家有帮助(is a good thing for everyone to share, we want to help)

说明：  空间变异函数，可用于土壤中有机质速效磷等的计算(Realization of two-dimensional variation function calculation)

给出蓝牙调频系统仿真模型，对于学习MATLAB/simulink 很有帮助(Bluetooth FM system simulation model is given for learning MATLAB/simulink helpful)

this code is for iris image enhancement using gaussian filter

水声OFDM通信系统仿真程序，包括信道估计、控制均峰功率比等关键技术，信道为多途信道。(The key technologies for the simulation of the basic OFDM communication system, including the scramble control both the peak power ratio, channel estimation, etc.)
