matlab 报错 Function 'subsindex' is not defined for values of class 'network'.

Error using subsindex

Function ‘subsindex’ is not defined for values of class

‘network’.

Error in feedforward (line 4)

net = train(net,traindata,t_lable);

变量列表中存在名字为train的变量，所以导致程序无法识别，修改变量名称由train改成train_test，然后再次调用train函数即可。

学习借鉴处：

net = train(net,p,t); <——————–Error here

y=sim(net,p);

By the way,

train is 5000x784 double

You’re trying to call the TRAIN function on the network; however, since

there exists a train variable in the workspace the line where the error

occurs is considered to be an attempt to index into the train variable

rather than a call to the TRAIN function. However, MATLAB does not know how

to use a neural network to index into a variable, so you receive that error.

Rename or delete the train variable and that call should work as a call to

the function rather than an attempt to index into the variable.
