matlab关于newff

Posted 2023-03-09

>> P=[0 1 2 3 4 5 6 7 8 9 10];
>> T=[0 1 2 3 4 3 2 1 2 3 4];
>> net=newff([0 10],[5 1],'tansig''purelin');
接着就出来
??? Error using ==> network.subsasgn
"layers1.transferFcn" cannot be set to non-existing function "tansig'purelin".

Error in ==> newff at 145
net.layersi.transferFcn = tfi;

P=[0 1 2 3 4 5 6 7 8 9 10];
T=[0 1 2 3 4 3 2 1 2 3 4];
net=newff([0 10],[5 1],'tansig','purelin');

%你个错误是（'tansig''purelin');中少了一个逗号 参考技术A newff(PR,[S1 S2...SNl],,BTF,BLF,PF)
PR -- R x 2 matrix of min and max values for R input elements
Si -- Size of ith layer, for Nl layers
TFi -- Transfer function of ith layer, default = 'tansig'
BTF -- Backpropagation network training function,
default = 'traingdx'
BLF -- Backpropagation weight/bias learning function,
default = 'learngdm'
PF -- Performance function, default = 'mse

答：
1.是
2.是
3.是，[S1,S2...SN]代表隐含层和输出层的数目
4.是

个人建议去MATLAB中文论坛下载视频教程，很不错~看过后肯定有收获
请参考 参考技术B net=newff([0 10],[5 1],'tansig''purelin');中的'tansig'与'purelin'之间少个逗号。
应该为net=newff([0 10],[5 1],'tansig','purelin');
