径向基神经网络相关函数：newrbe

>> help newrbe

newrbe - Design exact radial basis network (创建一个严格的径向基神经网络)

    This MATLAB function takes two or three arguments, P RxQ matrix of Q R-element

    input vectors T SxQ matrix of Q S-element target class vectors spread Spread of

    radial basis functions (default = 1.0)

    net = newrbe(P,T,spread)

P是R*Q 的输入矩阵，

T是S*Q 期望输出矩阵

spread 是标量，表示径向基函数的扩散速度，缺省值为1

举例（一）：

tic

P=-2:.2:2;

rand('sta
