plotting the training progress curve in Matlab

I have finished training a deep learning model, but unfortunately I forgot to save the curve which shows the training and validation progress. Could you please help me plotting this curve from the saved workspace in Matlab?

The commands I used to save the trained model are:

net=trainNetwork(augimdsTrain,lgraph,options); 

save net

[KSSV]

[net,info] = trainNetwork(augimdsTrain,lgraph,options); 

info would carry the information you wanted.

@KSSV But info is not saved in the workspace. Do you mean that I need to retrain the network? This will take about two days.

Is there any to plot the training/validation curve without retraining the network?

[KSSV]

I don't think that you can plot it now. The saved net contains only the last weights which have satisfied your fed criteria.

@KSSV Thanks a lot for your help. I will retrain the network from the beginning.
