我想把里面的P矩阵换成下面的数据：
p=[2616 810.33 485.33 4450.33; 1.3748 1.3205 1.239 1.1276; 45 85 18 22; 0.3 0.39 0.46 0.72];
t=[4.9 5.9 4.0 6.5; 4.5 5.3 3.6 6.1; 4.6 5.5 3.6 6.0; 2.3 2.2 2.7 3.6; 2.4 2.0 3.7 5.1; 2.4 2.8 3.9 5.4]; 
pp=[1974.67; 1.1948; 15; 0.62]; 
tt = [6.9; 6.2; 6.2; 4.3; 4.9; 5.2]; 

明明已经换了，可为什么出来的结果还是预测的原来的数据的值呢？？？是不是要建立一个叫做“MATLAB data file"的文件呢？这个文件在哪里创建呢？
还有一个问题就是我只有四个样本，是不是对于神经网络预测来说太少了呢？
哪位高手明白，请帮帮忙吧！谢谢呀！！
或者直接回复到我的邮箱<a href="mailtjjpurple120@tom.com" target="_blank" >jjpurple120@tom.com</A>也可以，谢谢！！

应该是由于样本少的原因！！样本太少用神经网络作预测达不到预期的效果是很正常的。

>我不仅得不到预期效果，而且得到的不是我后面提到的矩阵里的数据的预测值呀！而是在程序起点处的矩阵P里的数据的预测值，这是为什么呢？[em06]

不是吧？怎么可能呢？

你试试看这个能不能运行出来？？机子的matlab卸了，不能自己运行看，你自己看看吧！

<

>太感谢cai_chong啦！
<

>我运行过了，刚开始系统报错说，a=simuff(p1,w1,b1,'logsig',w2,b2,'purelin')中的P1未定义！我想了想，大概你是把PP笔误写成P1了吧？所以我把P1换成了PP，运行能够出来结果了：）

>但是，好像系统还是会报错的，下面是我运行结果,请cai_chong帮我看看啦，这样是不是还需要修改什么地方呢？
