Conversion to struct from double is not possible- Neural Network Pattern Recognition Toolbox
显示 更早的评论
Hello. I'm trying to execute the simplest example for Pattern recognition network, given in this link http://www.mathworks.fr/fr/help/nnet/ref/patternnet.html for iris flowers classification.
[x,t] = iris_dataset;
net = patternnet(10)
net = train(net,x,t);
view(net)
y = net(x);
perf = perform(net,t,y)
classes = vec2ind(y)
Error using struct Conversion to struct from double is not possible.
And it's the same error if I use the Neural Network interface. Can anyone help me, please? Thank you very much!

Please be so kind and post the complete error message. Most of all show us the line, which causes the error and explain the type of the used variables.

When I cut and paste his code (on a mac running R2014a and MacOS 10.9.3), I get this error:

I discovered that the cause of my replication of your error was the fact that I had redefined the 'softmax' function in my MATLAB workspace. There are a number of functions that would cause this error if you redefine them, such as: netsum purelin tansig dividerand mse adaptwb learngdm crossentropy softmax

I cut and pasted your code. It ran with no problem or messages.

I faced similar problem and it was resolved by resetting the workspace path list to default.

I was faced with the same problem When I run certain code occurs after you run this code I have to remove and re-install MATLAB

I found a solution for this problem. I think it is clashing with another function you may have.
To solve, go to Environment > Set Path, then move all the directories you included (from other toolboxes) to the end of the entries.
For me, worked like a charm!
