说明：  BP神经网络 训练 参数设置、调整 运算(BP TRAIN)

说明：  采用matlab编写的，采用二进制进行模式分类的程序，(prepared using Matlab, using binary for pattern classification procedures,)

说明：  抛物线法求解 方程的构造方法:给出[0,1]区间上的随机数(服从均匀分布)作为方程的根p*. 设你的班级数为a3,学号的后两位数分别为a2与a1,从而得到你的三次方程 例如:你的31班的12号,则你的方程是21x3+60x2+2x+a0=0的形式. 方程中的系数a0由你得到的根p*来确定. (parabolic equation method Construction Methods : given interval [0,1] on the random number (subject to uniform distribution) as the root equation p*. set up your classes at a3, after learning of the double-digit for a1 and a2, so you get the three equations for example : your 31 classes on the 12th, then your equation is 21x3 60x2 2x a0 = 0 forms. the equation coefficients a0 you get from the root of p* to determine.)

基于梳状导频的ofdm信道估计matlab程序仿真源代码(comb-based pilots ofdm channel estimation procedures Matlab simulation source code)

此matlab源程序是用来求解并联机器人的工作空间，最终以图形的形式表示出来(the workspace of parallel robot)
