做出一个矩形窗和布莱克曼窗，并分析它们的幅度和相频特性(the blackman window function amplitude and phase frequency characteristics)

分形维数计算的毯子算法matlab代码,毕业设计有用，搭建OFDM通信系统的框架。( Fractal dimension calculation algorithm matlab code blankets, Graduation useful Build a framework OFDM communication system.)

说明：  本代码提供了一个无线传感网路由协议的仿真，适合于初级学者。(This code provides a wireless sensor network simulation by the protocol, suitable for junior scholars.)

优化设计中常用的 牛顿法 和二次插值法 应用十分广泛 求解凸函数的极值和极值点问题(Commonly used to optimize the design of the Newton' s law and application of quadratic interpolation method for solving a wide range of convex functions and extreme points of the extremal problem)

给出了信号压缩通常的变换-量化-编码函数。DHT函数为离散DHT变换，是FFT变换的近似，其正反变换相同，克服了FFT复系数不利于存储的缺点。LLMAX函数给出了某x序列在固定比特下的最佳量化输出。熵编码函数为霍夫曼编码。(Gives the signal compression usually transform- quantitative- coding function. DHT DHT discrete transform function, the FFT transform approximation, the same positive and negative transformation, overcoming complex FFT coefficient is not conducive to storage shortcomings. LLMAX function x is given a fixed bit sequence in the optimum quantized output. Entropy coding function as Huffman coding.)

sift特征点匹配程序，实现特征点匹配，.m文件，直接在matlab中运行即可。(sift feature point matching process, to achieve feature point matching,. m files can be run directly in matlab.)

this program simulates 1D electromagnetic Maxwell equations with absorbing boundary condition to prevent reflection from the boundaries of the problem space. this is by using finite difference time domain method FDTD
