TEz cut off frequency of a metallic waveguide using FDTD

matlab2010开发环境，实现高斯金字塔，修改图片地址即可，测试成功，代码注释详细(matlab2010 development environment to achieve the Gaussian pyramid, modify the picture address test is successful, the code comments in detail)

matlab GUI的设计，具体的文档，图文并茂，比较容易学习(Matlab GUI design, specific documents, pictures, and relatively easy to learn)

ＢＰ神经网络算法是在ＢＰ神经网络现有算法的基础上提出的，是通过任意选定一组权值，将给定的目标输出直接作为线性方程的代数和来建立线性方程组，解得待求权，不存在传统方法的局部极小及收敛速度慢的问题，且更易理解。(Back Propagation ａｒｔｉｆｉｃｉａｌ ｎｅｕｒａｌ ｎｅｔｗｏｒｋｓ)

说明：  基于PSIM仿真软件，AC-DC变换，功率因数校正使用集成芯片UC3854进行仿真。(PSIM simulation software based, AC-DC conversion, power factor correction IC UC3854 using simulation.)

最小二乘的直线与曲线的拟合，以及利用matlab编程时多元线性回归(least square)

Included are the files wav1.m, wav2.m, wavecoef.mat and readme. wav2 function implements the tree structured wavelet transform of the input matrix, up to the given level of decomposition. Wav2 uses another function called wav1, which takes the well known wavelet transform of the given matrix. Daubechies wavelet coefficients are used for wavelet transform operation wahich is saved in wavcoeff.mat. (Included are the files wav1.m, wav2.m. wavecoef.mat and readme. wav2 function biennium max the tree structured wavelet transform of t he input matrix. given up to the level of decomposition. Wav2 use s wav1 another function called, which takes the well known wavelet transform of the given matrix. Daubechies wavelet coeffici separations are used for wavelet transform operation w ahich is saved in wavcoeff.mat.)
