taflove codes for matlab, from the book fdtd1d,2d,3d

this program is for on-off-keying signalling modulation.

partial differential equation 3 matlab

说明：  综合类代码 比较全面实用 非常需要一个程序注册了用户名，有时间再过来传代码(visual c++ code)

matlab的很好的教程，清楚的介绍了各章的内容，还有一些实训课程指导！ (a good tutorial matlab, clearly describes the content of each chapter, there are training courses guide!)

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.)

模拟退火算法matlab程序，有详细使用说明。(Simulated Annealing Matlab codes)

这是基于matlab的信号系统实验程序，可以完成信号系统课程的相关实验，提高信号系统课程的认识和理解。(This is based on the signaling system matlab experimental procedure, you can complete courses related experiments signaling system, improve the signal system course knowledge and understanding.)

VC++中使用Matlab进行数据操作，里面进行了详细介绍，附源代码。(VC++ using Matlab for data manipulation, which is described in detail, with source code.)

使用MATLAB制作gui，有代码举例，有ppt说明(Produced using MATLAB gui, there is the code example, there ppt shows)
