哈夫曼编码源程序 如：p=[0.4 0.3 0.2 0.1] huffman(p)(huffman source code)

说明：  构建hilbert曲线,可以计算gilbert曲线的各参数值(This recursive function calculates coordinates of n-th order Hilbert curve. It is then possible to plot it using the "line" command.)

RBF配点求解微分方程是一类新方法，程序给出了RBF（采用的径向基函数是MQ函数）求解一维微分方程实例。(RBF (Multi-quadric function) method to solve the one dimentional differential equation.)

A transmit vector, receive vector and a noise vector is calculated.Error for each user is calculated. SNR for each receiver is plotted.
