gmdh神经网络的详细程序，demo是主程序源码。(gmdh detailed procedures for neural networks, demo is the main source.)

说明：  圆拟合，通过已知的多组数据，拟合出最小误差的圆(Given a set of measured x,y pairs that a re supposed to reside on a circle, but with some added noise. A circle to these points, i.e. find xc,yc,R, such that (x-xc)^2+(y-yc)^2=R^2)

该程序为IEEE 802.15.4物理层仿真程序。工作频段为2.4GHz,信道模型为AWGN，仿真不同SNR情况下的BER。(This is a matlab programme of IEEE 802.15.4 which simulate the ber in different SNR values.The channel model is AWGN.)

利用matlab解方程的程序，可以用过微分方程，提供了集中方法(Using matlab solving equations can be used to differential equations, provides methods)

ask psk仿真，通信原理，包括文档以及源程序(ask psk)

Matlab是一个交互式的系统，它的基本运算单元是不需指定维数的矩阵，按照IEEE的数值计算标准（能正确处理无穷数Inf(Infinity)、无定义数NaN(not-a-number)及其运算）进行计算．(Matlab is an interactive system, its basic operation unit which is not specified dimension of the matrix, in accordance with the numerical calculation of IEEE standards (to correctly handle the infinite number of Inf (Infinity), no defined number of NaN (not-a-number) its operation) is calculated.)
