Function to plot an arc in matlab

说明：  共同学习，共同提高，资源共享 一个产生bpsk信号的例子，可以推出MPSK的调制基带信号(studying together, enhancing and sharing resources have BPSK signals an example, can be introduced MPSK the baseband signal modulation)

matlab程序，解决sift算法对图像特征点的检测，描述和匹配，特征点个数的计算以及程序运行时间，可与其他算法做比较，直接修改参数即可运行(matlab for image matching，include the time and the number of the interest points)

根据以下的平板光波导在波长为1550 nm时的折射率数据 1.作 出 不 同 波 导 芯 厚 度 d (0<d<15  m)对应的TE模式 与TM模式的色散图； 2.给出满足单模与双模传输的 波导厚度范围。 3.确定包层所需的最小厚度a 与b的值(The refractive index of the optical waveguide data at a wavelength of 1550 nm according to the following plate 1. do not make the same waveguide core thickness d (0 <d <15  m) corresponding to the TE mode And TM mode dispersion map 2. The single-mode and dual-mode transmission is given to meet the Waveguide thickness range. 3. To determine the required minimum thickness of a cladding And the value of b)

介绍了如何利用Matlab的代码生成功能将Simulink模型转换成目标语言模型的方法(The way that how to use the capability of Matlab in code generation to convert the mode1s constructed by Simulink to target language models is introduced)

说明：  利用子程序fast-lot.m,实现对该图像的变化及压缩，并和以为信号做dct后的图像质量相比较。(Using subroutine fast-lot.m, to achieve the changes and compression of the image, and after, and that the signals do dct compare the image quality.)

二维波导中计算反射系数，两边为PML，上下为PEC，波源为平面波(two-dimensional waveguide reflection coefficient calculated on both sides of the PML and bottom of the PEC, for the plane wave Boyuan)
