generate two pn sequencees and find correlations

smith圆图工具MATLAB版本,可以方便的进行阻抗匹配。(smith circle diagram tool MATLAB versions, you can easily carry the impedance matching.)

Basic program to print a text or a character for the basic learners..

经典matlab培训课件,非常好,简单易学.(Matlab classical training courseware, very good, easy to learn.)

说明：  利用FDTD模拟光子晶体光纤中的色散的程序，是在wang.m程序基础上改进之后计算色散的。(FDTD simulation of photonic crystal fiber used in the dispersion of the procedure is based on the improvements in the program after wang.m calculated dispersion.)

matlab/simulink通信建模与仿真实例精讲 非常详细(matlab/simulink communications modeling and simulation is very detailed Jingjiang)

说明：  matlab在通信原理中的应用，信道编码RS码仿真，希望大家能用得上！(matlab in Communication Theory in the application of channel coding RS code simulation, hope that we can useful!)

给定一个普通多项式p(x)，用列向量表示，阶次从高到低排列，此函数返回p(x)的切比雪夫多项式展开的系数，返回的的结果也是一个列向量，同样按切比雪夫多项式的阶次从高到低排列 另外该函数用cos(x)项傅里叶级数展开一个多项式( ChebyshevExpansion.m by David Terr, Raytheon, 5-26-04 Given a polynomial f(x) of degree n expressed as a row vector of coefficients of x^k with highest power on the left, expand f(x) as a sum of scalar multiples of Chebyshev polynomials, i.e. return the column vector of coefficients a_k with k running from n to 0 from top to bottom such that f(x) = sum_{k=0}^n{a_k P_k(x)}.)

说明：  自己编的付里叶变换，对学习者有很大帮助　(own series of the Fourier transform, to be of great help learners)

matlab实现CNN卷积神经网络，进行图像分类。(We can realize neural network with matlab, which will complete the classification of the image.)
