介质共形FDTD技术，可以很好地计算圆柱介质的谐振频率，也可以计算谐振腔中含有介质球的谐振频率(Dielectric conformal FDTD technique can be a good medium to calculate the resonant frequency of the cylinder can also calculate the resonant frequency of the resonant cavity containing a dielectric sphere)

主要描述Matlab优化实例。主要包括线性规划问题、foptions函数、非线性规划问题、“半无限”有约束的多元函数最优解、极小化极大（Minmax）问题、多目标规划问题、最小二乘最优问题和非线性方程(组)求解。 (The main description Matlab optimization instance. Mainly include linear programming problem, function foptions, nonlinear programming problem, " a semi-infinite constrained multi-function optimal solution, minimization great (MinMax), a multi-objective programming problems, least squares optimization problem and non- linear equation (group) to solve.)

一个模拟退火算法的例子，程序虽然简单但降温条件，降温函数，内外终止准则都有。可供初学者参考。(Example of a simulated annealing algorithm, the program is simple but cool conditions, cooling function, both inside and outside the termination criterion. Reference for beginners)

Watermark A visible or invisible signature embedded inside an image to show authenticity or proof of ownership. The hidden watermark should be inseparable the host image, robust enough to resist any manipulations while preserving the image quality. Thus through watermarking, intellectual properties remains accessible while being permanently marked.

利用firpmord和firpm函数设计双带通滤波器，其指标为，第一带通指标：f =4kHz,f =5 kHz ,f =3.6 kHz ,f =5.4 kHz 第二带通指标：f =6kHz,f =7 kHz ,f =5.6 kHz ,f =7.4 kHz 通带衰耗A <3dB，阻带衰耗A >40dB，抽样频率f =20kHz。(Double belt pass filter using firpmord and firpm function design, for its indicators, through the first area index: f = 4 kHz, f = 5 kHz, f = 3.6 kHz, f = 5.4 kHz The second bandpass indicators: f = 6 kHz, f = 7 kHz, f = 5.6 kHz, f = 7.4 kHz Pass band attenuation A < 3 db, stop-band attenuation A > 40 db, f = 20 KHZ sampling frequency.)
