matlab - 我的神经网络代码有困难

Question

我已经开发了我的代码，我想对我的输出进行后处理，但我收到了这个错误消息。

Attempt to reference field of non-structure array.

Error in mapminmax (line 74)
        if out2.no_change

Error in nm (line 20)
    output1 = mapminmax('reverse', output, Tar) 

下面是代码。

% Matlab program for predicting temperature using relative humidity has the
% input
Training_set = xlsread('Traindata.xlsx');
Testing_set = xlsread('Testdata.xlsx');
Input = Training_set(1:701, 2:4);
Target = Training_set(1:701, 1);

%normalise the input and the target
[Inp In] = mapminmax(Input');
[Tar Tr] = mapminmax(Target');

%create a back propagation network
Network = newff(Inp, Tar, [10], {'tansig', 'purelin'}, 'trainlm');

%train the network`enter code here`
Network = train(Network, Inp, Tar)
view(Network)
output = sim(Network, Inp);
error = output - Tar;
output1 = mapminmax('reverse', output, Tar)
