Real time Neural Network issue with "preparets".

Hi everyone,

I am trying to execute a real time neural network and, as long as I know, I need the preparets() function to “prepare” the variables for the neural network.

net= load('NARX_CMON');
X = tonndata(up,true,false);
T = tonndata(yk',true,false);  

%Execution of the net
[x,xi,ai] = preparets(net,X,{},T);
%where:
    %net is the neural network
    %X input data
    %T target data

yp(k) = cell2mat(neural_function(x, xi, ai));

The problem here is the following.

As I said before, I need to execute preparets () function, and for that, I need the “net” network class variable. To load that variable, I use, as you can see in the following code lines, the function load() .

But as you can see in the error picture that I attach below, Matlab says me that this variable is unsupported and thus, preparets() doesn’t work.

What am I doing wrong? What is going on? How can I solve this problem?

Thanks a lot,

Hi Erik,

Since the error originates from MATLAB Coder, I assume that you want to load a pretrained network for code generation. You can use the coder.loadDeepLearningNetwork function to load a network object. A similar issue has been addressed in the following MATLAB answer:

Please refer to the following documentation links for more information on loading pretrained networks for code generation using the coder.loadDeepLearningNetwork function:
