这是一个计算二维光子晶体能带的程序，采用平面波展开法模拟2维光子晶体的能带结构。( This is a program to calculate the Photonic Bands of two dimension Photonic Crystal with circular inclusions.)

说明：  Python的一个绘图模块，非常好用，体积有很小，可以替代matlab的大部分功能(Python in a drawing module, very easy to use, very small size, can replace most of the functions matlab)

Filler routines for different channels and sample sizes.

关于matlab主元分析的一个简单的实例，可供初学者参考学习。(Matlab PCA on a simple example of reference for beginners to learn.)

Simulink入门_MATLAB_大学课件_讲的很好(Simulink Getting Started _MATLAB_ University _ say good courseware)

编写M文件，创建如下图形窗口，分别绘制如下图所示的曲线。 （1）曲线y=sin(t)sin(9t)，要求采用红色，点线。横坐标取值范围[0~ ]，标注x轴、y轴并加标题。 （2）一组余弦曲线，其振幅分别为0.4，0.6和0.8。横坐标取值范围[0~2 ]。添加图例与标题。进入图形编辑状态，调整图例的位置。 （3）分别绘制peaks函数的曲面图和网格线图。对曲面图做平滑处理，并添加标题与colorbar。 (Write M file, create the following graphics window, curves were plotted as shown below. (A) the curve y = sin (t) sin (9t), require the use of a red dotted line. The abscissa in the range [0 ~  ], labeled x-axis, y-axis and a title. (2) a set of a cosine curve, and the amplitude was 0.4, 0.6, 0.8. Abscissa value range [0 ~ 2  ]. Add a legend and title. Into the graphical editing mode, adjust the position of the legend. (3) were drawn surface chart peaks function and grid line graph. Surface charts do for smoothing and add titles and colorbar.)
