说明：  基于运动模糊图像产生的原因，自编一个生产运动模糊图像的matlab程序，程序 需要输入模糊长度，默认模糊角度为0，包含一张图片(Based on the causes of motion blurred image, self production of motion blurred images of a matlab program, the program requires input fuzzy length, the default fuzzy angle 0)

学会用MATLAB编写程序； 学会一维搜索法； 精确的一维线性搜索法：0.618法； 非精确的一维线性搜索法：goldstein法；(Learn how to use MATLAB programming Society of one-dimensional search method precise linear one-dimensional search method: 0.618 law non-accurate one-dimensional linear search method: goldstein law )

误码性能仿真,主要对二元通信系统的发送和接收端的符号是否一致作出计算，并得到误码率。(bite error simulation)

卡尔曼滤波方法，有详细的介绍资料，也有源代码，自己有一部分的编写程序，欢迎参考(Kalman filtering method, a detailed presentation materials, but also the source code, they have to program a part, welcomed the reference)

利用matlab仿真，验证无码间串扰的条件，画出相关波形及眼图，并画出有噪声时的误码率特性曲线(Using matlab simulation, verification Uncensored crosstalk between conditions related to draw waveforms and eye diagram and draw there BER noise characteristic curve)

模式识别工具箱，很好用，matlab原程序(pattern recognizition toolbox)

产生右图所示图像f1(m,n)，其中图像大小为256×256，中间亮条为128 ×32，暗处=0，亮处=100。对其进行FFT： ① 同屏显示原图f1(m,n)和FFT(f1)的幅度谱图； ② 若令f2(m,n)=（-1）m+n f1(m,n)，重复以上过程，比较二者幅度 谱的异同，简述理由； ③ 若将f2(m,n)顺时针旋转90 度得到f3(m,n)，试显示FFT(f3)的幅 度谱，并与FFT(f2)的幅度谱进行比较； ④ 若将f1(m,n) 顺时针旋转90 度得到f4(m,n)，令f5(m,n)=f1(m,n)+f4(m,n)，试显 示FFT(f5)的幅度谱，并指出其与FFT(f1)和FFT(f4)的关系； ⑤ 若令f6(m,n)=f2(m,n)+f3(m,n)，试显示FFT(f6)的幅度谱，并指出其与FFT(f2)和 FFT(f3)的关系，比较FFT(f6)和FFT(f5)的幅度谱。(Generating an image f1 (m, n) shown in the figure, wherein the image size is 256 256, the intermediate light bar 128 32 0 = dark, bright Department 100. Its FFT: ① screen display picture f1 (m, n) and the FFT (f1) of the amplitude spectrum ② If so f2 (m, n) = (-1) m+n f1 (m, n), repeat The above process, comparing the amplitude spectrum of the similarities and differences between the two, brief reasons ③ If f2 (m, n) 90 degrees clockwise to get f3 (m, n), try to display FFT (f3) the amplitude spectrum and with the FFT (f2) comparing the amplitude spectrum ④ If f1 (m, n) obtained by 90 degrees clockwise f4 (m, n), so f5 (m, n) = f1 (m, n)+f4 (m, n ), try to display FFT (f5) amplitude spectrum, and pointed out its relationship with the FFT (f1) and FFT (f4) of ⑤ If so f6 (m, n) = f2 (m, n)+f3 (m, n) and try to display the FFT (f6) amplitude spectrum, and pointed out its relationship with the FFT (f2) and FFT (f3), comparing FFT (f6) and FFT (f5) amplitude spectrum.)

matlab详细入门教程，甚至安装运行的图文说明。有图有源码，相信对初学者很有帮助。pdf格式(matlab detailed introductory tutorial, and even graphic installation and operation instructions. There are pictures and source code, I believe useful for beginners. pdf format )
